: In the present study silver nanoparticles were synthesized biologically using the extracts of the seed of the plant Syzygium cumini (Jambolan). Phytochemical components in the extracts of the Jambolan seed were recorded. The stable silver nanoparticles were characterized by means of UV/Visible Spectrophotometer, Potentiometer and Scanning Electron Microscope. The nanoparticles exhibited maximum absorbance at 412nm in the UV spectra. SEM micrographs revealed that the synthesized nanoparticles were in the range 20-50nm. The antibacterial activity of the extracts of Jambolan seed increased in the presence of lower concentration of green synthesized silver nanoparticles of the eight bacterial pathogens used for antibacterial assay except Eschericha coli all the others like Klebsiella pneumonia, Vibrio parahaemolyticus, Plesiomonas shigelloides, Shigella spp, Streptococcus aureus, Pseudomonas aeruginosa and Vibro alginolyticus.
