Green Synthesis of AgNPs, Characterization and Antibacterial Activity from Salvia Leucantha Cav. Plant Aqueous Extract
R. Rajendran, A. Lakshmi Prabha
Abstract: The present study we proposed green synthesis of silver nanoparticles has been characterized and its antibacterial activity against human pathogen. The Lamiaceae family plant of Salvia leucantha Cav. for synthesis of silver nanoparticles and their efficacy in antibacterial activity against four human pathogens. The plant extract mediated synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, FT-IR, XRD, SEM and EDS. The UV-Vis spectra depicts surface Plasmon resonance peak present at 431nm. The three dimensional structure of silver nanoparticles was seen through SEM analysis. The observed FT-IR peaks showed functional groups and the stretch of bonds that responds to AgNPs synthesis. The XRD analysis showed that the silvernanoparticles are crystalline in nature and have face-centered cubic geometry. The synthesized nanoparticles showed remarkable antibacterial activity against Bacillus, Escherichia coli, Proteus vulgaris, and Streptococcus pneumonia. This present work provides a direct route of synthesis of environment benign silver nanoparticles via medicinally essential plant material.
