In the research field the green synthesis of metallic nanoparticle has attributed tremendous attention in recent years due to availability of plants and cost effective synthesis. Pisum sativum and Sauropus androgynus are plants with high biological activity due to its high content of proteins, vitamins, carbohydrates, lipids and secondary metabolites. In the present work we synthesized stable silver nanoparticles by reduction of silver nitrate solution (Ag+ to Ag0) using Pisum sativum peel and Sauropus androgynus leaf extract as the reducing agent. The synthesized silver nanoparticles were characterized by UV-Visible spectroscopy, FT-IR and X-ray diffraction (XRD). The nanoparticles were analysed with SEM for high resolution image of surface structure. Antimicrobial activity of synthesized silver nano particles against six bacterial strains such as Vibrio Cholerae, Salmonellatypi, Escheriacoli, Micrococcusluteus, Shigellaflexneri, Pseudomonas flurescens was screened.
