Plant based nanoparticles have many advantages over conventional physical-chemical methods and has various applications in medicine and biology. In present study, zinc oxide (ZnO) nanoparticles (NPs) were synthesized using Pistacia Vera L skin extract. The structural and optical properties of NPs were investigated by X-ray diffraction (XRD), FTIR spectroscopy, scanning electron microscope( FESEM) and ultraviolet-visible spectrophotometer (UV-Vis). The antibacterial potential of ZnO NPs was examined by paper disc diffusion method against Escherichia coli (E. coli) based on the zone of inhibition and minimal inhibitory indices (MIC). Change in color of the reaction mixture from brown to white indicated the formation of ZnO NPs. UV peaks at 320 nm , and XRD pattern matching that of JCPDS card for ZnO confirmed the presence of pure ZnO NPs. FTIR further confirmed the presence of bioactive functional groups involved in the reduction of bulk zinc sulphate to ZnO NPs. SEM analysis displayed the shape of NPs to be spherical whereas showed their size range from 30 to 78 nm
