Synthesis and Characterization of Gold Nanoparticles Embedded with Extract of the Plant Panicum maximum with Enhanced Antioxidant Behavior

Kanika Agarwal, M M Srivastava

Abstract :

The present piece of work deals with the green synthesis of gold nanoparticles embedded with ethyl acetate extract of plant Panicum maximum. The best parameters used for the synthesis includes NaAuCl4 salt solution (1 ml; 1 mM) and ethyl acetate extract of Panicum maximum (5 ml; 125 �g/ml). The results were confirmed by X–ray diffraction analysis, Scanning electron microscopy, Atomic force microscopy and UV–Vis spectroscopy. Antioxidant activities were determined using DPPH and Fenton bioassays. Gold nanoparticles embedded with ethyl acetate extract of Panicum maximum shows 36.2% enhancement in the antioxidant behaviour.
