Anaphalis neelgerriana  DC and Cnicus wallichi  DC belonging to the family Asteraceae (Compositae) are important medicinal plants indigenous to Nilgiris. Since the related species Anaphalis morrisonicola  and Cnicus benedictus  were reported for its anti cancer activities, the above mentioned plants were screened for In vitro  antioxidant activity. In vitro  antioxidant studies were carried out by DPPH, Nitric oxide and Hydrogen peroxide methods for the aerial part extracts of the plants. Different extracts were obtained from the aerial parts of the whole plant by successive solvent extraction and cold maceration process and subjected for In vitro  antioxidant activity studies. Among the extracts tested, the ethyl acetate extract of Anaphalis neelgerriana  DC and Cnicus wallchi  DC showed significant anti oxidant activity in all the above methods. The potent ethyl acetate extract should be tested for anti oxidant activity in animal models.
