Abstract

In the present study, Psidium guajava leaves were taken for synthesizing silver nanoparticles and checked their antibacterial activity against E.coli, Klebsiella, Pseudomonas, Staphylococcus and Acinetobacter. The plant extract was analysed for the detection of the presence of protein, carbohydrate, flavonoids, terpenoids, glycosides, steroids, saponins, phenols and tannins. In this present study, the antibacterial activity of green synthesized silver nanoparticles from guava leaf shows the zone of inhibition against all the five pathogens.
