Abstract
The simple and cost effective approach to synthesis of stable silver nanoparticle was achieved from the methanolic extract of Gloriosa superba rhizome. Research work has summarized as green synthesis of nanomaterial, identification of size and characterization of synthesized nanoparticle by SEM analysis, UV-visible spectrophotometer, Infrared spectroscopy, and X-ray diffraction. The synthesized nanoparticle revealed their antibacterial efficacy against Staphylococcus aureus, Bacillus subtilis and Salmonella typhi. The results found to be potent antibacterial activity at the different dosage level (25, 50, 75 and 100 µg/ml) among the concentration level, the 100 µg/ml was found effective and zone of inhibition 16.2±0.76, 13.3 ± 0.91 and 11.1 ± 0.94 mm against Staphylococcus aureus, Bacillus subtilis and Salmonella typhi respectively compared to the ciprofloxacin.
