Sustainable Green Synthesis of Polyherbal Silver Nanoparticles and Assessment of their Antibacterial Activity

Objective: The intent of the present endeavor was to formulate nanoparticles by an easy, green, and ecologically friendly synthetic process. Methods: Nanoparticles were synthesized by reducing the silver ions present in the solution of silver nitrate (0.01M) with aqueous poly herbal extract prepared from Seeds of Psoralea corylifolia, roots of Vetiveria zizanioides and roots of Cyperus rotundus. Silver nanoparticles were characterized using UV, FTIR, SEM and XRD examination. The antibacterial efficacy of yielded silver nanoparticles was examined at 10, and 20 mg ml−1 concentrations against two Gram’s positive (E. coli and B.subtilis) and Gram’s negative (P.aeruginosa and S.aureus) bacteria. Results: The synthesized nanoparticles had shown appreciable antibacterial activity on all the bacteria. Comparatively leading anti-bacterial effect was observed against Staphylococcus aureus and Escherichia coli. Conclusion: Thereby, our findings can be implemented to synthesize silver nanoparticles utilizing polyherbal extract in a quick, economical, and environmentally benign manner.
