The importance of traditional medicinal plants is increasing now a days because of various advantages over the synthetic drugs. Withania Coagulans dunal was studied for its antioxidant activity. Various physicochemical parameters were studied such as ash value, total ash, acid insoluble ash, water soluble ash, sulphated ash alcohol soluble extractive value etc. Various qualitative phytochemical tests were done for the presence of alkaloids, glycosides, carbohydrates, flavonoids etc. It was observed that 50% ethanol extract of withania coagulans contains carbohydrates, proteins, glycosides, steroids and sterols, anthraquinones and triterpenoids. The anti oxidant activity of Withania coagulans dunal was studied by DPPH and Nitric oxide method and it was observed that it has anti oxidant activity. It showed more activity in DPPH method than Nitric oxide method. Preliminary Phytochemical study of 50% ethanolic extract of the root parts is found to contain carbohydrates, protein, some steroids, anthraquinone, flavonoids, tannin, phenolic compounds and triterpenoids are present. The antioxidant activity was determined and the plant extract showed low activity nitric oxide free radical inhibition method and moderate activity by DPPH method. The activity was compared with rutin and ascorbic acid.
