Introduction: The benefits of Imperata cylindrica (I. cylindrica) leaves and their relationship to the content of phytochemical compounds have been widely studied. The aim of this study was to promote I. cylindrica leaves from Kertajati Subdistrict in Majalengka Regency in their use as a medicinal plant based on the four parameters, namely the content of total phenolic content, total flavonoid content, total tannin content, and antioxidant activity. The four parameters that become the basis for the benefits of the leaves were compared with the four parameters of the roots. Methods: Quantification of total phenolic content, total flavonoid content, total tannin content, and antioxidant activity used Folin-Ciocalteu, aluminium chloride, Fe(III) chloride and 1.10-Phenanthroline, and 1,1-diphenyl-2-pikrilhidrazil (DPPH) methods, respectively. All methods used visible spectrophotometric method. Results: The percentages of total phenolic content, total flavonoid content, total tannin content, and IC50 of antioxidant activity of I. cylindrica leaves extract were 9\% (GAE), 2.1\% (QE), 5.6\% (TAE), and 100.5 ppm, respectively. Then, the percentages of I. cylindrica roots extract showed the percentages of total phenolic content, total flavonoid content, total tannin content, and IC50 of antioxidant activity were 5.8\% (GAE), 0.64\% (QE), 3\% (TAE), and 241 ppm, respectively. Conclusion: The extract of I. cylindrica leaves contained the phenolic compound, namely flavonoids, tannins and other phenolic compounds, and had antioxidant activity. All parameters have been reported to have positive effect on health. Therefore, the leaves of I. cylindrica from Kertajati Subdistrict are discovered to have effects on health which are suitable to be promoted as a medicinal plant.

Introduction: Drimia numidica is a polyphenol-rich species that has antioxidant capacity, which makes it very important. Nevertheless, D. numidica has not been studied in depth. Moreover, its capsules have not been studied so far. This detailed study compared the values of total phenolic content and antioxidant activity of all D. numidica parts (scapes, flowers, bulbs, capsules, leaves, roots), from Edough Peninsula, Annaba, Algeria, using hydromethanol extracts and their fractions (cyclohexane, chloroform, ethyl acetate, and n-butanol). Methods: The total phenolic content was determined by Folin Ciocalteo assay, and the antioxidant activity by the following methods: DPPH, Reducing Powder, Phenanthroline, Silver Nanoparticles, CUPRAC, and ABTS. Statistical analysis was done using the ANOVA test and a correlation test (between antioxidant activity and total phenolic content). Results: The Ethyl acetate fraction was found the sample with the highest phenolic content. The same was true for the antioxidant activity in all tests except for the silver nanoparticles test in which cyclohexane extracts scored the best. Considering the methods used in general, there is a correlation between phenolic content and the highest antioxidant activity, but there are some methods that have not recorded any correlation. Conclusion: Choosing the appropriate method or extract/fraction type is extremely important. In addition, extracts of D. numidica parts could be an important natural alternative to antioxidants industrial.

The mask with natural extracts is more acceptable by consumers at present. The Chlorella sp. is one of the microalgae which contain the antioxidant compound. The research aimed to obtain the best concentration of Chlorella sp. in the manufacturing of masks and to evaluate the sensory, physical properties, chlorophyll a b, carotenoid and its antioxidant compound. Non-factorial Completely Randomized Design with 4 level treatments was used in this study with different concentrations of Chlorella sp. powder whereas MW0 (without chlorella powder), MW1 (0.4\% chlorella powder), MW2 (0.5\% chlorella powder), MW3 (0.6\% chlorella powder), triplicated. The parameter assay was observed for sensory (color, texture, and odor), physical properties (homogeneity, pH, spreadability, drying time), chlorophyll a, b, carotenoid and antioxidant activity. Based on the result of this study shows that the MW3 with 0.6\% of chlorella powder was the best treatment with sensory value (8.28, 7.08, 7.37); physical properties (homogenous, 5.3, 7.5 cm, 24-30 minutes), respectively. Meanwhile, chlorophyll a 0.67 mg/L, chlorophyll b 0.89 mg/L, total chlorophyll 1.63 mg/L, carotenoid 0.84 mg/L, the antioxidant activity of Chlorella sp. mask was 246.70 mg/L. Therefore, the present study suggested that the Chlorella sp. mask could be used in cosmeceutical products, and potentially as an antiaging.

Background: Montrichardia arborescens Schott (Araceae) is traditionally used for treating, among others, inflammatory conditions, but so far without scientific evidence. In this study, the fresh stem juice was assessed for its anti-inflammatory and antioxidant activities and phytochemical content. Methods: The stem juice{\textquoteright}s anti-inflammatory activity was evaluated using a heat-induced bovine serum albumin (BSA) denaturation assay and a hypotonicity-induced human erythrocyte membrane lysis assay. Its antioxidant activity was determined by a DPPH free radical-scavenging assay and a FRAP assay. Diclofenac and Trolox were used as reference compounds. Its phytochemical content was qualitatively explored by standard methods. Data (means {\textpm} SDs; n >= 3) were evaluated for statistically significant differences (p \< 0.05) using ANOVA with Bonferroni post hoc adjustments. Results: At >= 12.5\% (v/v), the stem juice inhibited BSA denaturation by 50\%-75\% and membrane lysis by roughly 90\%. At 0.20-7.0\% (v/v), it did not affect BSA denaturation but stabilized membranes by \> 50\%. The juice scavenged DPPH free radicals at an EC50 of 2.0 {\textpm} 0.2\% (v/v) and achieved at that dilution an antioxidant power of 2,616 {\textpm} 16 μM Fe2+ equivalents. All the effects were in the range of those found with diclofenac 50 μg/mL and Trolox 1.0-6.0 μg/mL. The stem juice contained phenolic compounds, flavonoids, tannins, alkaloids, saponins, and glycosides. Conclusion: The M. arborescens stem juice exhibited appreciable anti-inflammatory activities that might mainly be associated with the inhibition of the release of inflammatory mediators, along with notable antioxidant activity, which might be attributable to phytochemicals with known anti-inflammatory and antioxidant properties.

Background: Propolis is a wax-like resin which is produced by different types of bees by mixing resinous secretions of plants with beeswax and other products of bees{\textquoteright} metabolism. However, this natural product contains a group of compounds that are responsible for various propolis activities including antimicrobial, anticancer, antioxidant, antiviral, and others. This study aims to prepare different gel formulae that contain various concentrations of propolis extract using two different polymers and to evaluate their physical properties, antioxidant, and antimicrobial activities. Method: Propolis was extracted depending on the hydroalcoholic method; six different gel formulae (P-1 to P-6) were prepared with different concentrations of propolis extract (0.5, 1, and 1.5\%) using two different polymers; carbopol-934 and poloxamer-407, in concentrations of 0.5 and 25\% respectively. The formulae were evaluated physically for their visual appearance, pH, viscosity, spreadability, and physiological compatibility with the skin. The anti-microbial activities were investigated by well diffusion method against various bacterial species including Staphylococcus aureus (gram+), Pseudomonas aeruginosa (gram-), Enterococcus fecalis (gram+) and against one fungal species which is Candida albicans. Also, the antioxidant activity was determined utilizing 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay. Finally, a stability test was carried out for the chosen formula. Results: The six formulae (P-1 to P-6) were successfully prepared and evaluated and they were acceptable in their physical appearance and consistency, pH reading was in the range of 5.33{\textpm}0.08 to 5.72{\textpm}0.02 (p\>0.05), a study of the skin irritation revealed no undesirable side effect, while the viscosity was in the range of 128.99{\textpm}0.07 to 248.54{\textpm}1.04 Pa.s (p\>0.05), also the carbopol-934 containing formulae revealed good spreadability (1.495{\textpm}0.075 to 5.15{\textpm}0.35 mg.cm/s, p\>0.05), in comparison to poloxamer-407 containing ones. Both carbopol-934 and poloxamer-407 containing formulae exhibited antimicrobial activity but the P-3 formula had the largest inhibition zone against C. Albicans (16.1mm), and only P-2, P-5 and P-6 were active against pseudomonas aeruginosa (12mm in all), while P-2 had the largest inhibition zone against enterococcus fecalis (13.2 mm), P-2 and P-5 showed the largest activity against staphylococcus aureus (15.5 and 14.6 mm respectively). The carbopol-934-containing formulae exhibited higher antioxidant activity than those with poloxamer-407, and the best-calculated IC50 belonged to P-2 (1.19 mg/ml). Conclusion: All the prepared formulae showed antimicrobial and antioxidant activities with some controversial results. However, P-2 (1\% propolis extract and 0.5\% carbopol-934), was active against all types of the tested microorganism, and had the best-calculated IC50, in addition to that it was a stable formula.

The antioxidant activity of Annona squamosa (A. squamosa) leaf was carried out using methanol extract and fractionated extract namely n-hexane, ethyl acetate and residue. The antioxidant activity of methanol extract and fractionated was performed using the 1-diphenyl-2-Pycrilhydrazil (DPPH) method. The antioxidant activity test of methanol extract and fractionated n-hexane, ethyl acetate and residue yielded IC50 of 6.87, 169.99, 31.55 and 44.75 ppm. The ethyl acetate fraction extract with IC50 31.55 ppm was performed by column chromatography using silica gel G60 as the stationary phase and n-hexane: ethyl acetate as the mobile phase. The results of column chromatography obtained 181 fractions and were combined based on the stain pattern into 4 subfractions. Antioxidant test of each subfraction showed that the ASE 3 subfraction had the strongest antioxidant activity. Furthermore, the subfraction was analyzed using Gas Chromatography Mass Spectrometry (GC-MS). According, GC-MS data analysis showed that the third subfraction contained 19 phytochemical compounds, where 3 compounds having the highest concentration, namely 4,4{\textquoteright}-((p-Phenylene)diisopropylidene) diphenol, dodecanoic acid, methyl ester and phthalic acid, isobutyl 2-methylpent-3-yl ester.

Background: Suaeda vermiculata, a halophyte found in central Saudi Arabia, used as a remedy for jaundice, liver diseases, and viral infection. Study aim: Chemical identification and biological evaluation for the n-hexane extract of S. vermiculata. Methods: An assay of the antimicrobial and antioxidant potentials and contents of the volatile oil and n-hexane extract of the plant{\textquoteright}s aerial parts were analyzed through GC-MS analysis. Results: A total of 24 constituents representing 73.74 \% of the n-hexane extract were identified wherein bornyl acetate, γ-elemene, and phytol were major ratio. The n-hexane extract inhibited DPPH-radicals inhibitions at 27\% efficiency at 10 mg/ml concentration which was lower than the volatile oil DPPH-reactivity. The antimicrobial activity of n-hexane extract was relatively weaker than the volatile oil, except against Candida albicans that showed IZD values of 19 mm with MIC value at 5.2 mg/ml for the volatile oil while IZD value of 26 mm and MIC at 4.7 mg/ml was observed for the n-hexane extract. Conclusion: Despite high extractive value, the n-hexane as a solvent is not recommended for extraction as the oxygenated-terpenic components, considered responsible for antioxidant and antimicrobial activities were not fully extracted. The n-hexane extract which showed potent inhibition of C. albicans can be a source for further investigation for bioactivities of its constituents.

Introduction: Parthenium hysterophorus is a plant used in traditional medicine to treat health issues and which could be a source of phytochemicals with possible antioxidant activity without causing cytotoxic effects. Hence, this work was designed to evaluate its phytochemical profile, cytotoxicity, and antioxidant activity. Methods: The aqueous (AE) and ethanolic (EE) extracts of P. hysterophorus flowers were obtained by decoction and ultrasound, respectively. Their phytochemical composition was determined by colorimetric tests and RP-HPLC-MS analysis. Their cytotoxic activity was tested by a hemolysis assay. The antioxidant activity was evaluated with the Trolox equivalent antioxidant capacity (TEAC), 2,2-diphenyl-1- picrylhydrazyl (DPPH), and hydroxyl radical (-OH) scavenging assays. In addition, the effect of the extracts on the activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) from human erythrocytes, was evaluated. Results: The phytochemical screening of the AE and EE by colorimetric test showed the presence of flavonoids, steroids, triterpenes, saponins, coumarins, sesquiterpene lactones, tannins, and carbohydrates. In addition, the RP-HPLC-MS analysis identified some phenolic compounds such as flavonols, methoxyflavonols, flavones, methoxyflavones, and hydroxycinnamic acids. The hemolysis assay showed non-cytotoxic activity by AE, but EE exhibited a hemolytic effect. Furthermore, the AE and EE showed significant antioxidant activity to inhibit radicals in the TEAC, DPPH and -OH scavenging assays. Moreover, the SOD activity only showed a significant increase by AE. However, the two crude extracts increased the CAT activity, at the highest concentrations. Conclusion: P. hysterophorus has phytochemicals with antioxidant activity to inhibit radicals and increase the activity of antioxidant enzymes in vitro.

In vivo test was conducted to evaluate the effect of malondialdehyde (MDA) level in blood plasma during maximum physical activity treatment. In vivo test was done using 25 male Sprague Dawley rats in pre and post-test control group design. The phytochemical test of O. vulgare ethanol extract was showed some compounds, such as a flavonoid, alkaloid, triterpenoid/steroid, essential oil, and tannin, then in ethyl acetate and hexane. In vitro assay showed that O. vulgare extract has strong antioxidant activity with an IC50 value of 133.47 μg/mL. While in the in vivo test, the most effective dosage is 20 mg/200 gr B.W., represented by a significant decrease of MDA level (0.509 nmol/mL) before and after treatment. So, the ethanolic extract of clove has potency as an herbal antioxidant because of the low level of IC50 and can decrease the MDA level.

The current study was undertaken to examine the possible hepatoprotective effect of natural honey against carbon tetrachloride (CCl4)-induced liver injury in mice. A significant increase in the serum aminotransferases (ALT and AST) and alkaline phosphatase activity was noticed in mice exposed to CCl4. In addition to this, a significant decrease in total antioxidant capacity and antioxidant enzymes (catalase, glutathione peroxidase and superoxide dismutase) was observed in CCl4-induction group. However, treatment with honey (400 mg/kg b.w, 4 times/ week) clearly demonstrates significant hepatoprotective activities by lowering the liver marker enzymes towards the normal reference range and restores the antioxidant enzyme levels(p\<0.05). The effect of CCl4 was also noticed microscopically by alteration in liver tissue architecture. The administration of liver toxicant causes, hemorrhage, congestion, necrosis, edema and remarkable blood vessel dilation. Moreover, honey exhibited protective action against this haloalkane in tissue architecture as the severity of liver tissue alteration was significantly reduced (p\<0.05). The expressional pattern of P53 protein in groups treated with CCl4 only as well as honey plus CCl4 was statistically insignificant. In conclusion, this study reveals that natural honey has a remarkable protective effect against CCl4-induced liver toxicity at antioxidant enzyme, histological and protein expression level.

Background: Lepidium sativum L. (Family Brassicaceae) is known to possess different pharmacological properties. Objective: The genoprotective role of flavonoids of L. sativum methanolic seed extract (LSF) against cyclophosphamide (CP)-induced DNA damage, in somatic and germ cells of mice, as well as characterization of the flavonoidal content were carried out in this study. Chromosomal aberration analysis in somatic and germ cells were also included. Materials and Methods: Six mice groups were used for this study. Group 1 served as a negative control. Group 2 received oral LSF (100 mg/kg b.wt.) for 5 consecutive days. Group 3 served as a positive control by receiving a single intraperitoneal (i.p.) CP dose (20 mg/kg b.wt.). The three other groups were orally administered 25, 50 and 100 mg/kg b.wt. LSF, respectively, for 5 consecutive days. On the last day of treatment, the three groups received i.p. injection of CP (20 mg/kg b.wt.). Flavonoids were identified using spectral analysis. Results: LSF inhibited DNA aberrations in mice caused by cyclophosphamide dose dependently in the three groups with significant difference in the two groups that received doses of 50 and 100 mg/kg b.wt. The chromosomal aberrations inhibitory indices were calculated as 18 and 31 in mice somatic cells and 27 and 48 in germ cells, respectively. LSF was found to contain the flavonoids kaempferol, quercetin, kaempferol-3-O-α-L-rhamnopyranoside, kaempferol-3-O-β-D-glucopyranoside, and quercetin-3-O-β-D-galactopyranoside. Conclusion: LSF inhibited the DNA damage induced by CP in somatic and germ cells of mice dose-dependently. The antioxidant properties associated with flavonoids might account for the genoprotective activity.

Objective: This study aims to assess the phytochemical composition and antioxidant activity of the fruits (pulp and seeds) of Boscia senegalensis from the Ferlo zone in Northern Senegal. Material and Methods: Fruit collection of Boscia senegalensis was carried out in three Ferlo{\textquoteright}s localities: Tess{\'e}k{\'e}r{\'e}, Labgar and Ran{\'e}rou. The sample consists of 36 individuals selected randomly from each locality. The major chemical groups were determined by conventional methods using specific general reagents. The determination of total polyphenols and total flavonoids, the 2,2-diphenyl-1picrylhydrazyl (DPPH.) radical scavenging activity and ferric reducing of antioxidant power (FRAP) were evaluated by spectrophotometry. Results and Discussion: The results of the photochemical screening revealed the presence of saponins, alkaloids, sterols and triterpenes, flavonoids and polyphenols in both parts of the fruit (pulp and seeds). Assays carried out on extracts of pulp and seed powders reveals higher levels of total polyphenols and flavonoids in the pulp. The study of antioxidant activity has shown that hydro-ethanol extracts of pulp and seeds have a very interesting reducing activity, particularly in the pulp. However, we can see a weak antiradical activity of these extracts. The origin effect has a weak influence on the antiradical and reducing activity of the pulp and seed extracts. Conclusions: The biological activity of the harvested Boscia senegalensis extracts highlighted in this study could justify the traditional uses of this plant in the treatment of several pathologies. This fruit should be consumed in order to prevent few dietary imbalances or valorized in order to develop new bioactive compounds.

Backgound: Vernonia cinerea (VC) is a natural plant claimed to reduce cigarette smoking. Some pilot anti-smoking products with nicotine replacement, such as lozenges or gum, have been presented, but with some adverse effects. Thus, application of VC as a new-anti-smoking product is very challenging. Objectives: The aims of this study were to compare the active compounds; total phenolic compounds, total flavonoids and nicotine, and study antioxidant activity on scavenging 2,2{\textquoteright}-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) and 1,1-diphenyl-2-picryl hydrzayl (DPPH) radicals of extracts prepared by spray drying (SD) and freeze drying (FD) techniques for pilot hard candy. Methods: Raw VC materials of mixed parts, i.e., the stem, flowers and leaves, were made to form extracts by FD and SD techniques. Then, extract from the SD technique was manufactured industrially into hard candy containing glucose syrup and refined glucose. Total phenolic compounds, total flavonoids, nicotine, scavenging activity of extracts, VC hard candy and placebo candy were evaluated by folin-ciocalteau reagent, aluminum chloride colorimetric assay, high-performance liquid chromatography, ABTS cation decolorization and DPPH protocols. Results: Total phenolic compounds were significantly different between extracts, but total flavonoids and nicotine were slightly higher in SD extract. Antioxidant activity of both extracts on ABTS radicals was not significantly different, but the half-maximal inhibitory concentration (IC50) on DPPH radicals was significantly higher in SD extract when compared to the FD extract. Finally, total phenolic compounds, total flavonoids and nicotine, as well as scavenging activity could be detected in hard candy. Conclusion: VC can be used as an anti-smoking aid with nicotine replacement and anti-oxidant compounds in pilot hard candy.

Background: Free radicals are one of the causes that can cause premature aging and degenerative disease. To overcome this problem, the body needs antioxidant intake. Green tea (Camellia sinensis L.) leaves are one of the plants known as antioxidant agent due to its flavonoids and phenolic compounds or better known as catechin compounds. Catechin is polar flavonoid compounds so it is necessary to separate it from non-polar compounds so their antioxidant activity becomes effective. Objective: This study aims to determine antioxidant activity of ethanolic extract of green tea leaves and its fractions namely ethyl acetate and water fraction, and measure the total flavonoid content, total phenolic content and catechin content. Materials and Methods: Green tea leaves extracted using maceration method with 96\% ethanol. Fractionation was conducted using liquid-liquid extraction using a solvent of n-hexane, ethyl acetate and water. Screening of flavonoid and phenolic and antioxidant activity was performed against the ethanolic extract, ethyl acetate fraction and water fraction. Antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl method using ultravioletvisible spectrophotometry with ascorbic acid as standard. Results: The ethanolic extract, ethyl acetate fraction and water fraction contains flavonoids and phenolic compounds. The IC50 value of ethanolic extract, ethyl acetate fraction and water fraction were 9.017; 3.926 and 7.408 μg/mL consecutively. The ethyl acetate fraction also showed better antioxidant activity than ascorbic acid (4.855 μg/mL). Conclusion: The ethanolic extract, ethyl acetate fraction and water fraction showed very powerful antioxidant activity but ethyl acetate fraction has the best antioxidant activity.

Background: Traditional medicinal plants have been widely used to treat or manage various ailments for centuries in Lesotho. With an increase in multi drug resistance and undesired adverse events to current drugs challenges, there is a need for alternative drugs. Aim: In this study we aimed at the investigation of antibacterial, antioxidant and anti-inflammatory effects of Senecio asperulus and Gunnera perpensa roots extracted in three solvents of different polarities. Materials and Methods: Antibacterial activity was determined using the disc diffusion method, while antioxidant activity was determined using free radical scavenging of 2,2-diphenyl-1-picrylhydrazyl and the ferric reducing antioxidant power assay. The Lipopolysaccharide (LPS) stimulated RAW 264.7 mouse macrophage in vitro model was used to evaluate the anti-inflammatory activity of both plants. Resveratrol was used as a positive control. Results: Methanol extracts of Senecio asperulus inhibited microbial growth even at the lowest concentration of 50 μg/ml. Senecio asperulus dichloromethane extract was active on most bacteria with MIC{\textquoteright}s between 50 μg/ml and 500 μg/ml. However, the water and methanol extracts of Gunnera perpensa had no activity against all organisms tested. Aqueous extracts of Senecio asperulus and Gunnera perpensa showed free radical scavenging activity yielding EC50 values of 100 μg/ml and 25 μg/ml, respectively. The aqueous extracts of Senecio asperulus showed moderate anti-inflammatory activity from 50 to 200 μg/ml. while the methanol extract was at 200 μg/ml and with no cytotoxicity. No anti-inflammatory activity was observed from all Gunnera perpensa extracts using LPS-induced macrophages, this suggests that this species may be using other mechanisms for anti-inflammatory activity. Conclusion: The antibacterial, antioxidant and anti-inflammatory activities observed from water extracts of Senecio asperulus support its ethnomedicinal use for the management of inflammation related diseases.

Introduction: Madang gatal (Schima wallichii) Choisy is one of typical Indonesian plants that used traditionally as insomnia and hypertension drug. Background: The environment is highly polluted by free radicals which may contribute to the aging process of tissue and cause chronic diseases. The aims of the research were to study the phytochemical constituents and free radical scavenging activity of Schima wallichii stem bark. Materials and Methods: Extraction of S.wallichii stem bark was carried out by maceration method using methanol and then the methanol extract was partitioned using n-hexane, ethyl acetate and butanol successively. The methanol extract was then screened to determine the presence of different classes of secondary metabolites. The ethyl acetate fraction was subjected to silica column chromatography followed by exclusion chromatography on sephadex LH-20 to yield two partially purified isolates, SA and SE4. FTIR and GC-MS analyses indicated SA asa mixture of pentadecanoic acid, 14-methyl-, methyl esterand patchouli alcohol, while SE4 was made up predominantly of pentadecanoic acid, 14-methyl-, 13-hydroxy methyl ester. Free radical scavenging activity was performed by using2,2-diphenyl-1-picrylhydrazyl (DPPH) radical oxidation method. Results: The phytochemical screening indicated the presence of alkaloids, flavonoids, tannins, saponins, terpenes and quinones. All tested samples, methanol, n-hexane, ethyl acetate and butanol extracts showed strong antioxidant activity with IC50 values of 8.58, 17.36, 8.17 and 8.79 μg/mL, respectively. The isolates showed strong antioxidant activity with SE4 exhibiting an IC50 value of about 5.5 times stronger than quercetin used as a standard antioxidant.

Introduction: The extracts of the Pistacia species are known for their anti-inflammatory activity, including fruits and oil of P.\ atlantica. However, the inflammatory effect of the methanolic extract of P.\ atlantica leaves has not been studied. This work aimed at assessing the antiinflammatory and antioxidant activities of P.\ atlantica leaves extract in relation to phytochemical studies of flavonoids. Methods: The extract was obtained using sonication of leaves powder in 80 \% methanol. The analysis of phenolic compounds was carried out using thin-layer chromatography (TLC). The antioxidant activity was evaluated using DPPH, ABTS and FRAP assays. The anti-inflammatory activity was determined by the reduction of carrageenaninduced hind paw edema in mice. Results: The TLC revealed 3 glycosylated flavonoids and gallic acid derivatives. The flavonoids identified corresponded to rutin, quercetrin and other heterosides of quercetin, kaempferol and myricetin. Total phenolics and flavonoids contents were comparable for the male and female trees. The antioxidant activity did not show a significative difference between the two sexes, except for that evaluated by the FRAP assay which was significantly greater for the male tree leaves extract. The leaves extract permitted significative reduction of the edema at h3 and 6 in a dose-dependent manner (100 and 250 mg/kg), while diclofenac used as control reduced the edema at h 1.5. This difference could be explained by the pharmacokinetic and pharmacodynamic properties of diclofenac and P. atlantica leaves compounds. Conclusion: P. atlantica has a strong anti-inflammatory activity and constitutes a potential source for the development of new treatments.

Introduction: Ficus deltoidea is one of the common Malaysian medicinal plants and currently commercialized as raw ingredients in some local food products. However, those products do not discriminate the varieties of Ficus deltoidea used. Methods: FTIR-based metabolomics coupled with chemometric technique was applied to discriminate chemical components in ethanolic extracts of syconia of seven varieties of Ficus deltoidea namely; var. deltoidea, var. trengganuensis, var. kunstleri, var. angustifolia, var. bilobata, var. intermedia and var. motleyana. Unsupervised multivariate data analysis (MVDA) including principal component analysis (PCA) was used as to evaluate chemical variability among the seven varieties. For discrimination, orthogonal partial least square discriminant analysis (OPLS-DA) was applied, while partial least square (PLS) was used to evaluate the relationship between the alpha-glucosidase inhibition, antioxidant activity and Ficus deltoidea varieties. Results: As a result, OPLS-DA successfully discriminated the seven varieties. The FTIR fingerprints which were responsible for the discrimination includes 1729, 1705, 1448, 1095, 453, 443 cm-1. In addition, PPLS model demonstrated the correlation between var. kunstleri, var. deltoidea and var. intermedia respective chemicals fingerprints and their bioactivity (DPPH, FRAP and \α-glucosidase inhibition). Conclusion: The findings revealed that FTIR spectroscopy, in combination with MVDA, can be used for structural functional discrimination in relation to the sample bioactivity.

Oxidative stress can induce vascular endothelial dysfunction in diabetic and hyperlipidemia patients. Leucaena leucocephala (Lam.) de Wit has been reported of possessing antioxidant, antidiabetic and anticholiesterase activity; as well as the toxic substance called mimosine. Aims: To determine antioxidant effects of Leucaena leucocephala (Lam.) de Wit Leave extracts in oxidative stress induced vascular endothelial function. Methods and Material: Leave extracts were determined for antioxidant activity. Either or both of oxidized low density lipoprotein (oxLDL) and glucose were applied to induce oxidative stress condition in human umbilical vein cultured (HUVCs) to observe superoxide dismutase (SOD) activity, nitric oxide (NO) level and morphological changes. Results: Total polyphenol and flavonoid were 51.04 \± 0.91 mg GAE/g and 0.13 \± 0.01 mg catechin/g of dried weight (DW), respectively. Free radical reduction efficiency of crude extract observed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay showed IC50 value of 329.6 \μg of vitamin C equivalent/mg of extracts. Frap value was showed 428.54 \± 15.32 mM FeII equivalent/g of DW. The result observing in HUVCs showed that comparing to the control, SOD activity, NO and MDA level were maintained in 0.05 mg/mL of L. leucocephala treated group, but NO and MDA level were lowered when comparing with oxLDL and glucose-induced oxidative stress. No change was observed in 0.05 mg/mL of L. leucocephala treated group, comparing with control group. Conclusion: This study has been performed to exhibit the antioxidant activity of L. leucocephala in endothelium functions and has been found to have an appropriate concentration at 0.05 mg/mL in reducing oxidative stress condition in impaired fasting blood glucose patients. Nevertheless, the optimal level for toxic activity in inhibition of cancer angiogenesis should be further investigated.

Introduction: Endophytic fungi are becoming an important source of new natural bioactive products. Many interesting endophytic fungi have been isolated from traditional medicinal plants. Crocus sativus L. (saffron) is one of the most expensive and rarest spices in the world, used as a dye, aroma and for medicinal purposes. This study reports on the molecular characterization of endophytic fungi isolated from roots of saffron plants growing in Taliouine- Morocco, and the examination of the antibacterial and antioxidant activities of secondary metabolites extracted from these endophytes. Methods and Material: The fungi were isolated from sterilized saffron root fragments and identified using internal transcribed spacer (ITS) rRNA gene sequence analysis. Three endophytes were fermented and extracted with ethyl acetate (EtOAc) and chloroform (CHCl3). The antibacterial activity of fungi extracts was evaluated using the Agar Diffusion Method against six strains, Bacillus sp., Stenotrophomonas sp., Pseudomonas putida, Pantoea sp., Luteibacter sp. and Escherichia coli. The antioxidant activity was tested by using the \α,\α-diphenyl-\β-picrylhydrazyl (DPPH) analysis and \β-Carotene bleaching test (BCBT) methods. Results: Sixty fungal isolates were recovered and purified from saffron roots. ITS rDNA sequences were 99-100\% identical to three different species: Rhizopus oryzae, Aspergillus fumigatiaffinis and Aspergillus niger. Both Rhizopus oryzae extracts had high antibacterial activity against most of the bacteria tested, while Aspergillus niger and Rhizopus oryzae extracts showed an antioxidant capacity using DPPH and BCBT methods, respectively. Conclusion: The fungal endophytes inhabiting saffron roots could be a potential source of natural plant bioactive secondary metabolites especially for antibacterial and antioxidant purposes.

Objective: Thai medicinal plants were used as the traditional medicines and as part of everyday plants diet. Plants contain a mixture of phytochemical and exhibit a lot of functional food and medicinal properties. This project aims to investigate the potential of selected Thai medicinal plants according to the properties of their antioxidant and antibacterial activities. Methods: The eighteen plants were extracted using maceration method with 95\% ethanol. The antioxidant activity was evaluated by DPPH and FRAP assay. The total phenolic content was evaluated by Folin-Ciocalteu phenol reagent. The antibacterial activity was evaluated by agar disc diffusion method. The extract which exhibited high antioxidant and antibacterial activity was selected to observe morphological changes by the scanning electron microscope (SEM). Results: The extract of Caesalpinia sappan showed the highest activities on both antioxidant assayed by FRAP method and total phenolic contents, however, exhibited high antioxidant assayed by DPPH compared to Bauhinia strychnifolia extract. Moreover, the extract of C. sappan showed the excellent antibacterial activities against six pathogenic bacteria in Gastro-intestinal tract.

Aims: This study aimed to investigate and compare antioxidant activity, biochemical components and subchronic toxicity of brown rice kefir powder from three different coloured rice varieties; Khao Dawk Mali 105 (KDMLKP, white), Red Hawm (RHKP, red), and Hawm Nil (HNKP, dark purple), with cow milk kefir powder (CMKP). Medthods: Antioxidant activity performed by using ferric reducing antioxidant power (FRAP) assay and 2, 2\´-diphenyl-1-picrylhydrazyl (DPPH) assay. Biochemical components values including gamma-aminobutyric acid and alpha-tocopherol were determined using high performance liquid chromatography, but total phenolic compounds was detemined using the Folin-Ciocalteu reagent. Sub-chronic toxicity test, KDMLKP, RHKP and HNKP at the doses of 150 mg/kg were given orally to the rats every day for 90 days. Results: Antioxidant activity showed that brown rice kefir powders were significantly (p\≤0.05) higher than cow milk kefir powder. Interestingly, HNKP provided the highest FRAB value and the lowest IC50 of DPPH assay. HNKP had also the highest biochemical component values. Repeat administration of KDMLKP, RHKP and HNKP did not produce any symptoms of sub-chronic toxicity; mortality, hematological values, and blood biochemistry in the rats. Moreover, RHKP produced HDL increasing without CHO, TG and LDL changing in rats. Conclusions: These data indicate that brown rice kefir powders show no sub-chronic toxicity and exhibit more antioxidant activity and biochemical component values than cow milk kefir powder. Surprisingly, RHKP showed HDL increasing while HNKP had the highest potent antioxidant activity and biochemical components. Thus, both rice kefir powders are safe and probably a new biochemical resource for health.

The present study was carried out to examine the hypoglycemic effect of Silver Nanoparticles (SNPs) using ethanolic root extract of Clausena anisata (Willd.) Hook. f. ex Benth. A cost effective and eco friendly technique for green synthesis of SNPs from 1mM AgNO3 solution through the root extract was carried out. The biosynthesized SNPs were characterized using UV spectrophotometry, Field Emission Scanning Electron Microscopy (FESEM), X-ray Diffraction analysis (XRD), Energy Dispersive Spectroscopy (EDS) and Fourier transform infra-red (FTIR) spectrometry. DPPH assay was done to determine the antioxidant activity and for in vitro hypoglycemic activity glucose uptake by yeast cells, alpha amylase inhibition assay, adsorption capacity and glucose diffusion assay was performed. The SNPs of ethanolic root extract were found to be spherical in shape and up to 32.75 nm average in size. They showed alpha amylase inhibitory activity of 83.60\% at 500 g/ml. The glucose uptake by yeast cells was found to increase with an increase in concentration. The maximum glucose uptake was found to be 69.51\% at 10mM concentration. The molar concentration of glucose was directly proportional to the glucose binding capacity of extracts.The rate of glucose diffusion across the membrane was found to increase from 30 to 180 minutes. The DPPH scavenging activity was found to be potent (74.07\%) at 500 g/ml. The hypoglycemic effect exhibited by the SNPs was revealed by simple in vitro model of yeast cells, mediated by glucose adsorption, increasing glucose diffusion and glucose transport across the cell membrane.

Objective: To identify phytoconstituents present in an ethanolic extract of the leaves of Tabernaemontana divaricata and to evaluate its in-vitro antioxidant potential. Methods: The extract was subjected to gas chromatography- mass spectrometry analysis to identify phytoconstituents, and screened for hydroxyl, superoxide and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, reducing power and metal-chelating activity as a measure of potential antioxidant activity. Results: GC-MS analysis of the extract revealed the presence of 96 phytoconstituents, of which 17 are reported to be bioactive and 11 of these to possess antioxidant potential. When tested in-vitro, the extract exhibited the most potent radical-scavenging activity at a maximum concentration of 10 mg/ml, scavenging effects of 64\%, 67\% and 69\% and corresponding half maximal inhibitory concentration (IC50) values of 6.7 mg/ml, 6.8 mg/ml and 6.2 mg/ml on hydroxyl, superoxide and DPPH radicals, respectively. Ascorbic acid used as a standard (10 mg/ml) showed scavenging effects of 73\%, 73\% and 75\% and corresponding IC50 values of 5.3 mg/ml, 5.8 mg/ml and 5.2 mg/ml, respectively, on hydroxyl, superoxide and DPPH radicals. At 10 mg/ml, the extract and an ethylenediaminetetraacetic acid standard exhibited 68\% and 78\%, respectively, chelation of ferrous ions; at the same concentration, the reducing power of the extract and that of a butylated hydroxytoluene standard was found to be 3.855 and 4.308, respectively. Conclusion: These observations strongly suggest that the ethanolic extract of T. divaricata leaves has potent in-vitro antioxidant activity and thereby could act as a possible therapeutic agent for oxidative stressinduced pathological states.

Objective: The aim of the present study was to evaluate the antioxidant activity and total phenol and flavonoid content of different parts (peel, pulp and aerial parts) of Lagenaria siceraria. Method: Successive extraction was done by cold percolation method using solvents of different polarity viz. petroleum ether, toluene, ethyl acetate, acetone, water. Total phenol content was determined by Folin-Ciocalteu\’s reagent method and flavonoid was determined by aluminium chloride colorimetric method. The antioxidant assays evaluated were 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, 2, 2\’-Azino-bis-(3-ethyl) benzothiazoline-6-sulfonic acid (ABTS) radical cation scavenging activity and Ferric reducing antioxidant power. Results: L. siceraria peel possessed maximum phenol and flavonoid content in acetone and toluene extracts respectively. FRAP was maximum in acetone extract of peel. The peel extract demonstrated stronger DPPH activity with IC50 value of 111 \μg/ml followed by pulp extract. The same extract was effective in scavenging ABTS radical with an IC50 value of 39 \μg/ml while other parts were ineffective. Conclusion: This work demonstrated good antioxidant activity of L. siceraria vegetable cultivated in India and recommends that the peel of this vegetable may be of interest from a functional point of view as a major source of natural antioxidant.

Introduction: Skin darkness may be cosmetically undesirable for some people. Plant-derived materials traditionally used for skin lightening may produce satisfactory results. Besides innate tyrosinase activity, oxidative stress also plays an important role in skin darkness by activating tyrosinase. Therefore, herbal extracts with strong anti-tyrosinase and antioxidant activities could be considered as efficacious skin lightening agents. The aims of the present study were to determine the anti-tyrosinase and antioxidant activities of Thai medicinal plant extracts indigenously used as skin toners. Methods: The activities of seven Thai medicinal plants; Zingiber cassumunar Roxb., Phyllanthus emblica Linn., Tagetes erecta Linn., Centella asiatica, Raphanus sativusvar. Longipinnatus Linn., Cassia fistula Linn. and Butea monosperma (Lam.) Taub. were investigated using the DOPA-chrome method to determine anti-tyrosinase activity and the DPPH free radical scavenging assay to determine antioxidant activity. Results: With respect to tyrosinase inhibitory activity, P. emblica, B. monosperma and R. sativusvar. Longipinnatus extracts at a concentration of 1.67 mg/mL showed strong activities with the percentage of tyrosinase inhibition at 48.38\±4.77, 46.92\±3.77 and 42.85\±6.54\%, respectively. In addition, P. emblica and B. monosperma extracts also exhibited high antioxidant activities with the IC50values on 33.47\±1.24 and 33.57\±1.92 mg/mL, respectively. Conclusion: Based on tyrosinase inhibition activity and DPPH radical scavenging assays, the herbal extracts of P. emblica and B. monosperma show promise as potential skin lighteners in cosmetic formulations.

Introduction: Accumulation of reactive species higher than permissible limits in biological systems may lead to various degenerative disorders due to oxidative damage. Materials and Methods: Oxidation is a serious concern faced by the food industry causing deterioration of shelved-food quality. Antioxidant compounds like polyphenolics scavenge such free radicals and thus protect against oxidative stress. Consumption of polyphenol-rich plants as dietary component confers protection against such cellular damage. Results: Present study explores antioxidant capacity, total phenolic content (TPC) and total flavonoid content (TFC) of different extracts prepared from various parts of Moringa oleifera Lam. Higher TPC, TFC and antioxidant activity was shown by methanolic extracts followed by aqueous, petroleum benzene and chloroform extracts.The present study suggests that all the extracts might act as radical scavengers to certain extent possibly due to presence of polyphenolic compounds. Conclusion: M. oleifera exhibits strong antioxidant activity and could serve as prospective source of natural antioxidants to food and health industries.

Background: Seabuckthorn (SBT) is a high altitude medicinal plant with vast history of use in traditional medicinal systems such as Tibetan and Chinese systems. SBT leaves have shown range of pharmacological properties suggesting their importance to be used for product development. Objective: The aim of this study was to compare 75\% ethanolic extracts of male and female SBT leaves on the basis of antioxidant activity, total phenol content and high performance thin layer chromatography (HPTLC) estimation of \β-sitosterol and ursolic acid. It also involved comparison of total phenol contents of successive soxhlet extracts (pet ether, chloroform, ethyl acetate, ethanol, and aqueous) of above leaves. Materials and Methods: Antioxidant activities and total phenol contents of the extracts were evaluated by using 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging assay and Folin\–Ciocalteu reagent based assay, respectively. Results: Male leaf extract was found to show signifi cantly higher antioxidant activity and total phenol content than that of female leaves. Furthermore, the successive extracts of male leaves showed higher phenol contents than that of female leaves. However, it was not signifi cant in case of pet ether and chloroform extracts. In HPTLC estimation, concentration of \β-sitosterol in female leaf extract was observed to be less than that of male leaf extract. However, ursolic acid concentration was found to be almost same in both the type of leaf extracts. Conclusion: The results suggest the need for developing standard quality control profi le of SBT leaves, especially for product development.
