Antioxidant Activity of Croton zambesicus Muell. Arg Seed Extract

Abstract

The present study was designed to investigate the antioxidant activity of Croton zambesicus Muell. Arg seed extract and fractions (Family: Euphorbiaceae). The antioxidant property was assessed by testing for DPPH free radical scavenging activity. Potential antioxidant activity was presented by methanolic extract. C. zambesicus showed high DPPH value (83.21 ± 0.05). Crude extract was fractionated using separation funnel, the five fractions were obtained are hexane, chloroform, ethyl acetate, n-butanol and water which represented antioxidant activities equal to 46.2 ± 0.1349, 45.1 ± 0.0116, 49.9 ± 0.0337, 40.45 ± 0.2290 and 62.7 ± 0.0006 respectively.
