Biosynthesis of silver nanoparticles using methanolic extracts of Acorus calamus, and assessment of its antioxidant and antimicrobial activity
Vinita Chawla and Dr. Sangeeta Sathaye
Acorus calamus (Sweet flag) is a wetland perennial monocot plant, the scented leaves and rhizomes of which have been traditionally used as medicine against different ailments like, fever, asthma, bronchitis, cough and mainly for digestive disorders such as bloating, colic, and poor digestive function. In addition, Ayurvedic medicine Calamus is also valued as a "rejuvenator" for the brain and nervous system. The present investigation was undertaken to prepare the plant extract, to analyze it for its phyto constituents, synthesize the Silver nanoparticles biologically, and to check the antimicrobial and antioxidant activity of the synthesized silver nanoparticles. The silver nanoparticles synthesized were characterized by UV Vis spectrophotometry, Fourier Emission Scanning Electron Microscopy (FESEM), X - Ray Diffraction (XRD) and Electron Dispersive Spectroscopy (EDS). The nanoparticles exhibited antioxidant activity and antimicrobial activity against Gram positive and Gram negative bacteria.
