In-Vitro Antioxidant Activity of Leaves of Ipomoea fistulosa Linn

Free radicals are implicated for more than 80 diseases including Diabetes mellitus, arthritis, cancer, ageing etc. In treatment of theses diseases, antioxidant therapy has gained an utmost importance. Current research is now directed towards finding naturally occurring antioxidant of plant origin. In Indian system of medicine Ipomoea fistulosa is an important medicinal plant. The in-vitro antioxidant activity of various extracts of Ipomoea fistulosa leaves was investigated. The extracts and the reference standard, butylated hydroxyl toluene (BHT) were evaluated for DPPH, nitric oxide, superoxide and hydroxyl radical scavenging activity. The methanolic extract exhibited significant antioxidant activity but petroleum ether and chloroform extracts of Ipomoea fistulosa did not show any significant antioxidant activity in comparison with standard (BHT).
