Abstract :
The antioxidant activity of the tuber extract of Habenaria edgeworthii (commonly known as Vrddhi) has been studied against a long lived 2,2-diphenylpicrylhydrazyl (DPPH) radical at room temperature. The tuber extract has been utilized for the synthesis of stable gold nanoparticles at room temperature under very mild conditions. The synthesized gold nanoparticles were characterized by spectroscopic and electron microscopic techniques.
