The phytochemical analysis of the medicinal plant Kalanchoe pinnata was carried out to evaluate the antioxidant potential. Alcoholic extracts of the leaves was subjected to in vitro antioxidant activity screening models such as inhibition of metal ion chelating activity and hydrogen peroxide scavenging activity.EDTA is used as a standard for metal ion chelating activity and for hydrogen peroxide scavenging activity Ascorbic acid is used as a standard. In all the models studied , the extracts showed potent antioxidant activity, thereby augmenting it into the present day system of medicine.
