Özet: Biological methodologies utilizing microorganisms and plants or plant extracts for metal nanoparticles union have been recommended as important options in contrast to concoction strategies. The utilization of plant materials for the preparation of nanoparticles could be more worthwhile, in light of the fact that it doesn't require expound procedures, for example, intracellular amalgamation and numerous purging advances or the maintenance of microbial cell societies. An endeavor has been made to build up a straightforward quick method for bioreduction of silver nanoparticles (AgNPs) using bark concentrate of Butea monosperma and to assess the antimicrobial action of prepared silver nanoparticles against different microorganisms. Characterization was determined by using UV-VIS spectroscopy and the antimicrobial activities of the produced Ag nanoparticles were resolute using the disc diffusion assay method.  UV-Vis range of the aqueous medium holding silver nanoparticles revealed an absorption peak at 478 nm. The formed silver nanoparticles revealed profound antimicrobial drive against different microorganisms like Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa and Streptococcus pneumonia. Present examination shows Butea monosperma has solid potential for the synthesis of silver nanoparticles by quick reduction of silver particles (Ag+ to Ago). Present investigation suggests strong proof for basic, fast and prudent course to integrate AgNPs using aqueous bark concentrate of Butea monosperma. The formed AgNPs showed strong antimicrobial potential. The results were compared with the effect of antibiotics. And were found to be more potent than antibiotics. It was observed that the growth rate was strongly inhibited by the presence of small concentration of nanoparticles.
