Phytochemicals, antioxidant and the bioactive compounds present in the fruits of Solanum dasyphullum was investigated. Several phytochemicals such as saponins, tannins, alkaloids, flavonoids, steroids and cardiac glycosides were detected. A total of 172 compounds were identified by GC-MS. Phenols, spermine, 2, 5- dimethylfuran and 2-methyl-1-hexadecanol were all identified. These compounds are known to have antioxidant property which may be responsible for the antioxidant property of the fruit extract. It was observed that the fruits extract exhibit antioxidant properties. The scavenging activity increases with the concentration of the extract with the following percentage scavenging activity; 200µg(90%),133µg (78%), 100 µg(69%), 67 µg(48), 33 µg(26.7%), 20 µg(18), 7 µg(7%). Compounds identified in the fruits of Solanum dasyphylum can be isolated and used as an antioxidant. Keywords: Solanum dasyphylum, oxidation, antioxidant and extracts.

Background: Medicinal plants are having immense potential to cure various health ailments and used as drugs and remedies for the treatment of various diseases since civilization. Medicinal property of these plants lies in their secondary metabolites which covered various classes like phenols, alkaloids, flavonoids, tannins, etc. Besides this, these secondary metabolites serve as a prototype to synthesize the new synthetic drugs. </P><P> Objective: The present study was carried out to evaluate the antioxidant and antibacterial activity of leaves extracts of Calotropis procera and Calotropis gigantea and characterization of their bioactive metabolites by Fourier Transform Infrared (FTIR) spectroscopy and Gas Chromatography-Mass Spectroscopy (GC-MS). Methods: Methanol, petroleum ether and water were used for the extract preparation using cold percolation method. Antibacterial activity was assessed by agar well diffusion assay. The antioxidant activity of both the plants of Calotropis species was carried out by using different assay. Phytochemical analysis was carried out by using FTIR spectroscopy and GC-MS analysis. Results: Methanol extract of both the plants was found to possess highest antioxidant potential in comparison to other extracts. Methanol extract of C. gigantea and aqueous extract of C. procera showed the maximum antibacterial activity against the tested bacterial strains. FTIR analysis of plants extracts indicates the presence of phenolic compounds, alkanes, carboxylic acids, aldehydes, aliphatic and aromatic amines, allene, sulfoxides, phenyl ester nitrocompounds and imines. GC-MS analysis of C. procera aqueous extract showed the presence of R-limonene, mannosamine, tridecane, 1-bromo-, 2-propenoic acid, tridecyl ester, pentatriacontane and 1-hexacosene as major phytochemicals. C. gigantea methanol extract indicated the presence of hentriacontane, eicosane, 3,3- dimethylnonadecane, pentacosane, 1-hexacosene, pentatriacontane and clocortolone as major phytochemicals. Conclusion: This study provides a systematic base for isolation of the novel bioactive phytochemicals from the Calotropis plant species and to evaluate their efficacy especially for antioxidant and antibacterial activities.

Leptogium rivurale is a flooded jelly skin lichen as the surface becomes jelly on wet. It is a cyanolichen with a cyanobacterium Nostoc. In this present study, Leptoguium rivurale were collected from Kodaikanal and extracted using methanol and distilled water. Qualitative analysis of phytochemicals from the extracts showed the presence of carbohydrates, glycosides, phenols, terpenoids, saponins, and proteins. The methanol extract was found to inhibit the α-amylase enzyme activity better than aqueous extract. The methanol extract was found to have better DPPH radical scavenging activity and anti-inflammatory activity than aqueous extract. Then the extract was subjected to GC-MS analysis. The molecules obtained through GC-MS analysis were subjected to in-silico molecular docking simulation using AutoDock software. Cyclohexanol and oxirane were the potential drug candidates identified.
