Objective:The present study is deals with the green synthesis of silver (AgNPs), iron oxide (α-Fe2O3NPs) and core-shell (Ag-α-Fe2O3CNPs) nanoparticles using the aqueous extract ofAlstonia scholariswithout any catalyst, template or surfactant or any intermediate under ultrasound cavitation technique. The purpose was to facilitate the high level of dispersion with increase in rate of reaction. Further AgNPs and α-Fe2O3NPs were used to synthesis Ag-Fe2O3CNPs in aqueous extract ofAlstonia scholarisunder controlled ultrasound cavitation technique.Methods:The size of AgNPs and Ag-Fe2O3CNPs can be tuned by optimizing various reaction parameters. UV-visible, X-ray diffraction spectroscopy (XRD), Transmission electron microscopy (TEM), Field emission scanning electron microscope (FE-SEM) and Fourier transform infra-red spectroscopy has been used for the characterization of silver and core shell Ag@Fe2O3nanoparticles. TEM images clearly show the formation of core shell nanoparticles with spherical morphology.Result:Fourier transform infra-red spectroscopy analysis revealed that carbohydrate, polyphenols, and protein molecules were involved in the synthesis and capping of silver, iron oxide and Ag@Fe2O3CNPs.

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.
