Invitro antioxidant activities of methanolic extract of whole plant of Pedalium murex (Linn.)

Abstract

In vitro antioxidant activities of methanol extract of tuberous root of Ipomoea digitata (Linn.) was investigated. The free radical scavenging activity to evaluate by DPPH (2, 2-diphenyl -1- picryl hydrazyl) method, superoxide anion scavenging and iron chelating activity. DPPH radical scavenging activity of Methanolic extract and reference standard Rutin IC₅₀ values was found to be 240 mg/ml and 480 mg/ml, superoxide anion scavenging activity of methanolic extract and reference standard Quercetin IC₅₀ values was found to be 99 mg/ml and 60 mg/ml and iron chelating activity of methanolic extract and reference standard EDTA IC₅₀ values was found to be 440 mg/ml and 65

mg/ml respectively. The above result of possess good an antioxidant activity when compare to the above all standard.
