GREEN SYNTHESIS OF SILVER NANOPARTICLE BY USING TINOSPORA CORDIFOLIA LEAF EXTRACT AND ITS ANTIMICROBIAL PROPERTYAbstract
Tinospora cordifolia is one of the best medicinal plants holds most prominent place in Ayurveda Rasayana herbs and it also known as “rejuvenate herbs” because of its medicinal properties. It has been found to exhibit anti-microbial properties, its anti-microbial feature found in root, stem, and leaf extracts on pathogenic micro-organisms. Green synthesis of AgNPs can potentially eliminate chemical agents’ problems that may have adverse effects, thus making nanoparticles more compatible with the eco-friendly approach. The present study focuses on the green synthesize of silver nanoparticle, which was conducted by Tinospora cordifolia leaf extract. Characterization of silver nanoparticle was performed by Scanning Electron Microscopy. Silver nanoparticles exhibit strong anti-microbial effect against gram-positive and gram-negative bacteria such as Escherichia coli, Pseudomonas syringae, Staphylococcus aureus and Enterococcus faecalis. Both methanolic and ethanolic extract showed good antimicrobial activity against all the bacteria whereas methanolic extract had wide range of anti-microbial activity than ethanolic extract.
