Abstract

Tuberous roots of Decalepis hamiltonii (Dh) are consumed in southern India as pickles and beverage for their health benefits. The antioxidant potential of the roots was measured using various in vitro assays. Among the extracts, the methanolic and aqueous extracts showed high antioxidant activity measured as scavenging of DPPH, superoxide and hydroxyl radicals. Both the aqueous and methanolic extracts inhibited microsomal lipid peroxidation and exhibited strong reducing power and metal chelating activity. The antioxidant activity did not correlate with the phenolic content of the extracts. These results demonstrate the antioxidant potency of the root extracts which could be the basis for its alleged health promoting potential of Dh. The roots of Dh could serve as a new source of natural antioxidants or nutraceuticals with potential applications to reducing the level of oxidative stress and related health benefits.
