Abstract

Drugs from plant source are safe, effective with no adverse effects.Plants are the better candidates for nanoparticle synthesis because they are free from toxic chemicals and provide natural capping agents. The nanoparticles produced from plant parts are more stable and the rate of synthesis is rapid. Leaf extracts of Galinsoga parviflora has pharmacological properties such as antibacterial, antifungal, antioxidant, anti-inflammatory and antitumor, and also used in the treatment of eczema and lichens. The characterization of biosynthesized GPAgNPs was carried out by using analytical parameters such as UV-Visible spectral analysis, SEM with EDS imaging, FTIR analysis, and Zeta potential Particle size analyzer. The average sizes of nanoparticles were found to be 55nm by SEM and the obtained nanoparticles are of good stability.

Keywords: Galinsoga parviflora, Methanolic extract, silver nanoparticles.
