Objective: To evaluate the antioxidant capacity of Chuquiraga spinosa extracts and prevention of carrageenan-induced inflammation in mice. Methodology: Experimental design: plant species, erythrocytes and male BALB C53 mice, were considered as biological material. Antioxidant capacity was evaluated in 50\%, 70\%, 96\% and aqueous ethanolic extracts by 2,2-Diphenyl-1-Picrylhydrazyl reduction, malondialdehyde inhibition in oxidized erythrocytes with H2O2 and correlating with polyphenol content equivalent to gallic acid/gram dry extract. Inflammation was evaluated by inoculating carrageenan 2\% in "subcutaneous air bag" of mice: 1) White, 2) carrageenan, 3) dexamethasone 2 mg/kg, 4-6) ethanolic extract 70\% doses 100, 250 and 500 mg/kg respectively; determining nitric oxide, malondialdehyde, total proteins, albumin, leukocytes in exudate and histological changes. Results: Alkaloids, flavonoids, terpenes, phenolic compounds, tannins, carbohydrates, triterpenes, steroids and sesquiterpene lactones were identified; aqueous extract presented greater reduction of 2,2-Diphenyl-1-Picrylhydrazyl (CI50 = 58.99 μg/mL), ethanolic extract 70\% presented greater inhibition of malondialdehyde in erythrocytes (CI50 = 16.44 nm/mL); It was observed that the higher the amount of polyphenols, the greater the reduction of 2,2-Diphenyl-1-Picrylhydrazyl (r=-0.909) and the greater the inhibition of malondialdehyde (r=-0.781). With 500 mg/kg of 70\% ethanolic extract there was greater anti-inflammatory effect inhibiting malondialdehyde, nitric oxide, albumin, total proteins and leukocytes in 55.55\%, 81.92\%, 41.20\%, 31.51\% and 32.45\% (p\<0.01) respectively and less infiltration of leukocytes and lymphocytes in air sac membrane. Conclusion: The extracts of aerial parts of Chuquiraga spinosa showed antioxidant capacity correlated to polyphenol content. The 70\% ethanolic extract prevented inflammation in mice in a dosedependent manner.

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: Terminalia bellerica belonging to family combretaceae is one of the major components of {\textquotedblleft}Triphala{\textquotedblright}, an Ayurvedic formulation. Objective: To evaluate antioxidant potential in the ethanolic extract and its active fraction (chloroform, ethyl acetate, n- butanol and aqueous fraction) from fruits and leaves of Terminalia bellerica. Materials and Methods: Folin-Ciocalteau method and aluminium chloride method was used to quantify total phenolic and flavonoid content respectively in ethanolic extract and their fractions from fruits and leaves of T. bellerica. The antioxidant activity was evaluated using total antioxidant activity, DPPH, FRAP and total antioxidant activity methods. Results: Total phenolics (254.72{\textpm}3.03 mg/g GAE and 227.52{\textpm}1.38 mg/g GAE) and flavonoids (64.77{\textpm}1.24 mg/gm RE and 75.57{\textpm}1.38 mg/gm RE) content was higher in ethyl acetate fraction of both fruits and leaves sample of T. bellerica, respectively. The order of free radical scavenging activities was ethyl acetate fraction \> crude ethanolic extract \> n-butanol fraction \> chloroform fraction \> aqueous fraction. Similarly, ethyl acetate fraction of both fruits and leaves exhibited more antimicrobial activity as compared to that of ethanolic extract as revealed from agar well diffusion method with diameter of zone of inhibi{\textlnot}tion of 14.0{\textpm}1.41 mm, 21.0{\textpm}1.41 mm, 14.0{\textpm}1.41 mm, 14.5{\textpm}0.71 mm in fruits and 18.0{\textpm}1.41 mm, 22.5{\textpm}2.12 mm, 15.5{\textpm}2.12 mm, 14.5{\textpm}3.53 mm in leaves against B. subtilis, S. aureus, E. coli, K. pneumoniae, respectively. MIC values for fruits were 3.125 mg/ml, 0.375 mg/ml, 3.125 mg/ml, 3.125 mg/ml and for leaves were 1.5625 mg/ml, 0.19 mg/ml, 0.78 mg/ ml, 0.78 mg/ml against B. subtilis, S. aureus, E. coli, K. pneumoniae, respectively. Conclusion: The present study provides the evidence for comparative antioxidant and antibacterial potential of ethanolic extracts of fruits and leaves of T. bellerica. . Moreover, leaves can be promoted to be used for therapeutics and natural antioxidants.

Background: Plants have a well-developed defensive machinery for minimizing the reactive oxygen species (ROS) associated damages in the form of enzymatic and nonenzymatic antioxidants. The in-vitro mechanism of antioxidant action of plant extracts may involve direct inhibition of the ROS generation or ROS scavenging. The antioxidant activity of the extracts may be due to active constituents alone or the combination of constituents. However, the amount of constituents are known to vary according to the change in environment. Method: In our study, antioxidant activity of Amaranthus caudatus L. from two different sites (elevation sites) was investigated at three stages, (vegetative, pre flowering and post flowering) using ethanolic extract (EtOH). Result: The phenolic and flavonoid content increased at all stages from site 1 to site 2. The total reducing power, Ferrous reducing antioxidative power (FRAP), diphenyl picryl hydrazine (DPPH) radical scavenging assay, superoxide dismutase scavenging (SOD) assay and hydrogen peroxide (H2O2) scavenging activity increased from site 1 to site 2 at all the three stages. Conclusion: The results reveal that the altitude and the growth stage have a significant effect on antioxidative potential of Amaranthus.

Objective: To enhance solubility of ethanolic extract of Andrographis paniculata by solid dispersion technique and to perform formulation and evaluation of solid dispersion tablet. Materials and Methods: Solid dispersion of Andrographis paniculata extract has been prepared by solvent evaporation technique using soluplus and PEG 6000. Prepared solid dispersions have been evaluated for various micromeritic properties. The tablets of solid dispersion were prepared by direct compression technique and were evaluated for various physical tests and in-vitro dissolution study. Results: The study showed that prepared solid dispersion has good flow property and compressibility. The solubility of extract was found to be more from solid dispersion prepared by using soluplus than that of prepared by using PEG 6000. The rate of drug release was found to be higher in acidic buffer at pH 1.2 as compared to that of in phosphate buffer at pH 6.8. Conclusion: The study concludes that the solid dispersion tablet of ethanolic extract of Andrographis paniculata can be effectively prepared using soluplus by solvent evaporation techniqu
