Introduction: Medicinal plants have a broad range of active components that have been used by most of the world's population to cure a plethora of maladies. Many innovative approaches have been used in recent years to identify, proliferate, develop, and evaluate medicinal plants for use in modern and traditional medical formulations, as well as in drug discovery. Methods: We looked for papers on green synthesis of AgNPs (silver nanoparticles)by various plant extracts on Google Scholar and Pub Med. "Ag Nanoparticles," "Plant Extract," and "Antimicrobial" were the search terms. Eligibility testing was done in a standardized, non-blinded way. First author, year of publication, subject related to green synthesis of silver nanoparticles from plants, Ag nanoparticles from leaf, peel and flower extract, antimicrobial properties of leaf, flower and peel extract were all retrieved from each paper. Results: A PubMed search yielded 310 results. In all, 25 papers were considered in our review, which were published between 2011 and 2022. There were no human studies reported. Most of the studies considered (12/25; 63.15 percent) were carried out by Indian research groups. In seven studies, flower was used for the extraction of silver nanoparticlesand in 6 studies, leaf extract was used for the extraction of silver nanoparticles while in 12 studies, peel extract was used for the extraction. The size of synthesized silver nanoparticles ranged from 4nm to 90nm. The most used method for characterization included UV-Vis, TEM (fifteen studies), SEM (five studies), FTIR, XRD, Raman scattering (one study),Cell viability assay (one study). The antimicrobial properties were carried out by MIC assay.Almost all the studies showed positive MIC values against the studied microbes. Conclusion: Green synthesized nanoparticles have been shown to be persistent, versatile, and are safe. Green synthesized silver nanoparticles can clearly compete with and sometimes outperform commercial antibiotics for the management of microbial diseases. As a result, these environmentally friendly silver NPs may be employed as an effective antibacterial agent against pathogenic microbes that are multidrug resistant.
