Abstract

Green synthesis of nanoparticles in pharmaceuticals has gained much interest due cost-effective, environmental friendly and non-hazardous approach in the procedures. In this study, a method for green synthesis of silver noanoparticles from Couroupita Guianensis was established and evaluated for its antibacterial activity. The silver nanoparticles were prepared from different concentrations of silver nitrate to obtain maximum yield. The formation of the silver nanoparticles was confirmed by UV-Visible range spectroscopic analysis. The synthesized silver nanoparticles were characterized for its size and morphology by SEM and TEM analysis. The SEM and TEM revealed green synthesized nanoparticles were monodispersed, polycrystalline and polyhedral in the nature. The FTIR spectrum confirmed the interaction of the plant phytoconstituents with the silver nanoparticles which act as capping agent for the silver nanoparticle and enhance its shelf-life. The green synthesized silver nanoparticles possessed efficient antibacterial activity against Gram negative bacteria, E. coli and Pseudomonas aeruginosa.
