Abstract : The antibiotic-resistant strains become major issue in pharmaceutical and medical treatments of pathogenic microorganisms. Some medicinal plants provid evidence that even against some antibiotic-resistant bacteria, they could represent potential sources of novel antimicrobial medicines. The goal of this study was to look at the antibacterial potential of green synthesized silver nanoparticles using Aerva javanica (Burm.F.) leaves extract against four microbial isolates as Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli by agar well diffusion assay and showed significant antimicrobial activity particularly against Bacillus subtilis. The synthesized nanoparticles were characterized by UV-VIS, XRD, FT-IR. Scanning electron microscope (SEM) was used to study the morphology and Energy dispersive X-ray and was applied to confirm the presence of Ag NPs. Chemical constituents of Aerva javanica (Burm.F.) were characterized using liquid chromatography ion trap mass spectrometry (LC-IT-MS) and found high amount of flavonoid and phenolic compounds such as Isorhamnetin, Kaempferol, Quercetin, and Ferulic acid and anti-oxidant vitamin E, derivative of (+)-Cymarin and Oleamide.
