Dr. Somkant V. Jawarkar*1, Sanmati D Shete2, Dr. Sandeep R. Kane2

In this study, rapid, simple approach was applied for synthesis of silver nanoparticles using Bacopa monnieri leaf extract. The plant extract acts both as memory enhancer agent. To identify the compounds responsible for reduction of silver ions, the functional groups present in plant extract were investigated by FTIR. Various techniques used to characterize synthesized nanoparticles are DLS, and UVeVisible spectrophotometer. UVVisible spectrophotometer showed absorbance peak in range of 400-800nm. The silver Nanoparticles of Bacopa monnieri leaf extract showed DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging activity. Present study confirmed that it is a simple, rapid, one step, eco-friendly, nontoxic and alternative conventional physical/chemical methods, only 15 min were required for the conversion of silver ions into silver nanoparticles at room temperature, without the involvement of any hazardous chemical which shows prominent antioxidant property.
