The present research was aimed to investigate the antimicrobial potential of biologically synthesized silver nanoparticles from leaf extract of Eucalyptus globules against certified pathogenic microorganisms Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Shigella, Staphylococcus aureus and also acne inducing bacteria, using agar well diffusion method. Highest antimicrobial activity (20 mm) against Staphylococcus aureus was recorded with methanolic extract of Eucalyptus globules leaves in comparison to other extracts. Phytochemical analysis of crude extract revealed the presence of alkaloids, carbohydrates, flavonoids, saponins, steroids, soluble starch, terpenoids and tannins. The silver nanoparticles synthesized from the methanolic extract using silver nitrate showed peak at 375 nm. The characterization of nanoparticles for size, shape and nature using X.. View More»
