English abstract A novel green source Ziziphus mauritiana fresh young leaves was opted to synthesize silver nanoparticles and analyze its antibacterial activity. The bioactive compounds present in the plant extracts reduced silver ions to NPs, indicated by change in colorfrom red to dark brown. In this study, we have successfully synthesized nanoparticles using Z.mauritiana aqueous leaf extract as a reducing agent and the reaction process of synthesized nanoparticles was monitored by UV-Vis spectroscopy. The UV-Vis absorption peak showed maximum adsorption at 420 nm confirmed the silver nanoparticles synthesis. Further characterization was carried out by FTIR and the results recorded a downward shift of absorption the bands between 400 to 4000 cm-1indicates the formationof silver nanoparticles. Finally, the present research was exploited to study the antibacterial activity of synthesized nanoparticles produced Z.mauritiana was studied using different pathogenic bacteria such as Salmonellasp., Proteus sp., Bacillus sp., Klebsiella pneumonia and E.colifrom the well diffusion results, the synthesized silver nanoparticles displayed the best antibacterial property as compared to the antibiotic has been reported in this paper. To the best of our knowledge, this is the first report that the Z.mauritiana aqueous extract facilitate the synthesis of silver nanoparticles and also exhibits antibacterial activity
