Abstract

Calotropis procera belongs to the family Asdepiadaceae, which has been used as a folk medicine. Although there are some reports showing the plant effective in folk use but there were no scientific reports for antioxidant activity of petroleum ether extract. The leaves of Calotropis procera were air dried, grounded and soaked with diethyl ether for 48 hours than the solvent was evaporated and the oil extract was investigated for antioxidant ability by measuring total phenolic content, total flavonid content and reducing ability, the data obtained were compared with Pyrogallol, Qurcetein and ascorbic acid which they consider as standard for these experiment. The result shows high antioxidant activity for Calotropis procera extract.
