title: Free radical scavenging potential of Picrorhiza kurrooa Royle ex Benth.
abstract: For assessing free radical scavenging potential of P. kurrooa, the antioxidant activity of P. kurrooa extract was studied by lipid peroxidation assay using rat liver homogenate. The extract (1 mg/ml) showed marked protection (up to 66.68%) against peroxidation of liver phospholipids. Besides, reduced glutathione showed very encouraging activity. The extract also exhibited significant scavenging activity. Thus augmenting the wide use of plant in the indigenous system of medicine, which may partly be due to antioxidant and free radical scavening activity of the extract.
