The antioxidant activity of the tuber extract of Habenaria intermedia (commonly known as Rddhi) has been studied against a long lived 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical at room temperature. The phytochemicals present in the tuber extract have been utilized for the green synthesis of Rddhi tuber extract conjugated gold and silver nanoparticles at room temperature under very mild conditions.
