Aims: The purpose of this study was to determine the content of the secondary metabolite compound in the flower extract of Rhinachantus nasutus (L.) Kurz (RnK); The potential of the extract as a radical scavenger of 2,2-diphenyl-1-picrylhydrazyl (DPPH); and its potential as an anti-inflammatory by inhibiting protein denaturation with bovine serum albumin (BSA). Results: Phytochemical screening results on the ethanolic extract of R. nasutus flowers revealed the presence of steroid glycosides, alkaloids, flavonoids, phenolics, and tannins. The extract has a strong ability to scavenge DPPH radicals with an IC50 value of 77.07 {\textpm} 0.05 mg/L. Besides that, the ethanol extract has very strong anti-inflammatory activity, with an IC50 value of 13.88 {\textpm} 0.2 mg/L. Conclusion: According to these findings, the ethanolic extract of R. nasutus flower can be used as an alternative anti-inflammatory drug.

Background: Andrographis producta (Acanthaceae) is endemic to Western Ghats, India, traditionally used by native people for the control of various ailments including intestinal worms, to relieve constipation and also used to eliminate phlegm in women during postpartum. Objective: To investigate the chemical compounds in root, stem and leaves of A. producta and their antioxidant properties. Method: The phytochemical contents were determined using spectrophotometric methods and chemical profiling of root, stem and leaf extracts was carried out using GC-MS. Further, extracts were investigated for their antioxidant capacities using in vitro DPPH radical scavenging and FRAP assay. Results: The total phenolics (163.61 mg GAE/g), flavonoids (35.11 {\textpm} 0.53 mg QE/g) and tannins (84.52 {\textpm} 0.07 mg TAE/g) were highest in stem compared to leaf and root. Stem was exerted superior antioxidant capacities in both DPPH (EC50 3.58 mg/ml) and FRAP assays (1.742 {\textpm} 0.02 OD at 1mg/ml) and were comparable to standards. GC-MS analysis revealed total 89 chemical compounds including phenolics, flavonoids, terpenoids and organic acids. 2-Methoxy-4-vinylphenol (0.70 \%), 2,4-ditert- butylphenol (9.74 \%), phytol (10.32 \%), 5-hydroxy-7,8-dimethoxyflavone (11.42 \%), gammasitosterol (8.32 \%), salvigenin (12.09 \%), solanesol, (2.92 \%), and alpha-terpinene (4.58 \%) were important bioactive compounds found in significant amount. Conclusion: The present investigations indicate that various parts of A. producta can be explored as good source of antioxidants due to the presence of phenolics and flavonoids. The meticulous assessment of bioactive compounds from A. producta would be great contribution in field of medicine.

The present study aimed to evaluate phytochemical and antioxidant activity (in vitro and in vivo) of Origanum vulgare (L.) ethanolic extract. The phytochemical test was assessed using the Clule method in ethanol, ethyl acetate, and hexane. In vitro evaluation of antioxidant activity was determined by radical scavenging assay using DPPH (2,2-diphenyl-1-picrylhydrazyl) as an artificial free radical activity. 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.

Background: The aqueous decoction of the stem back of Mangifera indica L. has been traditionally used for the treatment of various illnesses among them includes anaemia. Aims: The aim of this study was to investigate the anti-anaemic properties of the standardized stem bark extract of M. indica in animals with 2,4-dinitrophenylhydrazine-induced haemolytic anaemia. Methods and Material: An in vivo animal model was used in this experiment. 2,4-dinitrophenylhydrazine was used to induce haemolysis and treatment was done with three different concentrations (25, 50, and 100 mg/kg b.wt) of the plant extract. Astifer\® was used as a positive control. Haematological parameters such as PCV, HGb concentration, and TLC were performed to determine the present of phytoconstituents within the crude extract. Results: PCV and HGb concentration was increased significantly (p\<0.001) at a dose of 50 and 100 mg/kg b.wt respectively while no significant (p\>0.05) effect was observed at a dose of 25 mg/kg b.wt. TLC was decreased significantly (p\<0.001) at a dose 100 mg/kg b.wt when while no significant (p\>0.05) effect was observed at a dose of 25 and 50 mg/kg b.wt respectively. GC-MS analysis revealed the presence of 15 compounds among viz: 2,2-Dimethoxybutane, N-Acetyl-Alpha-D-glucosamine, 1,2-Benzenediol, Phenol, 2,4-bis(1,1-dimethylethyl)-, Vitamin E, Pentadecanoic acid, 13-methyl-, methyl ester, 2-Ethylacridine, Benzofuran-6-ol-3-one, 2-(4ethoxycarbonyl)benzylidene-, 9-Octadecanoic acid, (E)-, 2,4,6-Cycloheptatrien-1-one, 3,5-bis-trimethylsilyl-, and Benzo[h]quinoline,2,4-dimethyl-. Conclusion: The results of our present finding suggest the significant anti-anaemic properties of standardized stem bark extract of Mangefera indica L. This finding highlights the potentials of the extract M. indica in the treatment of haemolytic anaemia.
