Abstract : Boerhaavia diffusa L. (Family: Nyctaginaceae) commonly known as Punarnava is an herbaceous, spreading vine widely distributed in the tropical and subtropical regions in the world. The plants are a rich source of vitamins, minerals, protein and carbohydrate. The present study was carried out to determine the concentration of some bioactive phytochemicals (ascorbic acid, carotenoids, total phenolics, protein and carbohydrate) and their antioxidant activity in punarnava. Results showed the values for ascorbic acid (16.75±1.72 and 18.86±1.12 mg/100g of Fresh Weight), carotenoids (1.36±0.10 and 1.98±0.11 ìg/g of Fresh Weight), protein (122.975±6.27 and 134.45±6.23 mg/g of dry weight) and carbohydrate (56.67±5.77 and 60.11±5.23 mg/g of dry weight) for aqueous and methanolic of root extracts of B.diffusa respectively. Methanolic root extracts showed greater antioxidant activity than the aqueous extracts using DPPH method.
