Antioxidant Potential of Methanolic Extract Tuberous Root of Ipomoea digitata (Linn)

Abstract

In vitro antioxidant activities of methanol extract of tuberous root of Ipomoea digitata (Linn.) was investigated by various method. The antioxidant activity was evaluated by nitric oxide radical scavenging activity, total antioxidant activity and estimation of flavonoids. The methanolic extract of Ipomoea digitata and reference standard ascorbate IC₅₀ values was found to be 880 μg/mL and 410 μg/mL in nitric oxide radical scavenging activity. Total antioxidant activity of methanolic extract was evaluated by phosphomolybdic acid method and reference standard ascorbate IC₅₀ values was found to be 50 μg/mL and 410 μg/mL and flavonoid content of methanolic extract was found to be 2.112 mg/g. It is concluded that the free radical scavenging activity of the methanolic extract of Ipomoea digitata responsible for the therapeutic properties.
