An important herbal plant Withania somnifera was evaluated for its antioxidant potential changes in leaves and roots. The main antioxidant constituents Non-enzymatic (ascorbic acid, alpha-tocopherol and reduced glutathione) and enzymatic (superoxide dismutase, ascorbate peroxidase, catalase, peroxidase and polyphenol oxidase) antioxidants were estimated from both leaves and roots. The analyses were carried out in the field-collected samples. It was found that plant contain a significant quantity of non-enzymatic and enzymatic antioxidants in these organs. But, the quantity varies in both organs. The roots contain more amounts of these antioxidants than leaves. Here from this study, it can be concluded that, the root of Withania somnifera are good source of nonenzymatic and enzymatic antioxidant components.
