Abstract :
The antioxidant efficacy of the rhizome extract of Polygonatum cirrhifolium (Mahameda) has been studied against a stable 2, 2-diphenylpicrylhydrazyl (DPPH) radical at room temperature. The chemical constituents present in the rhizome extract have been utilized for the one step synthesis of stable gold nanoparticles at room temperature under very mild conditions. The synthesized gold nanoparticles were well characterized by surface plasmon resonance spectroscopy, high resolution transmission electron microscopy, x-ray diffraction and FTIR studies and a mechanism for the synthesis and stabilization of gold nanoparticles has been described.
