GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES USING EXTRACT OF Anisomeles malabarica (L.) AND EVALUATION OF ITS ANTIMICROBIAL ACTIVITIES

Abstract

The phytochemical analysis carried out on the aqueous leaves extract of Anisomeles malabarica showed the presence of a maximum number of phytochemicals. The green synthesis of SNPs was done successfully using aqueous leaves extract of A.malabarica. Primary confirmation of color change from pale yellow to brown color was observed at 420nm recorded by UV- Visible spectroscopy and detailed characterization was carried out using UV-Visible spectroscopy, XRD, SEM. Present investigation also suggests that the green synthesized SNPs are exerting in vitro toxic effects on human microbial pathogens. Antibacterial studies of SNPs were highly attractive with different inhibition zone capacity when compared with aqueous leaves extract. Similarly Antifungal studies of SNPs also showed significant antifungal activity against the fungus when compared with aqueous leaves extract. The zone of inhibition formed is maximum in Aspergillus niger and showed best antifungal activity when compared with Candida albicans
