Abstract: The main aim of this study is to evaluate the Green synthesis of silver nanoparticles synthesized from aqueous plant extract of Ricinuscommunis and study its Antimicrobial activity. The synthesized silver nanoparticles were characterized by UV-VIS spectroscopy, Fourier Transform Infra-Red spectroscopy, Scanning Electron Microscopy and X-ray diffraction. The antimicrobial activity of synthesized silver nanoparticles was compared with their respective plant extract by agar well diffusion method was calculated. The zone of inhibition varied in range of 12 to17 mm with 100 μg/ml silver nanoparticles concentration. The antimicrobial activity of synthesized silver nanoparticles was higher than that of the standard drug i.e. streptomycin (for bacteria). The synthesized nanoparticles of Ricinuscommunis have shown good antimicrobial efficacy as compared to plant extract and may prove to be better antimicrobial agent against wide range of microbes.
