Abstract
Recently, a substantial body of literature provides strong evidence to support the potentials of Crataeva magna (CM), plant and its extracts in various pathological conditions. Thus, the CM plant extract at various concentrations were prepared and antioxidant activity was evaluated. The fresh leaves and bark of CM were collected and various extracts such as n-Hexane, Chloroform, Ethanol and aqueous extract were prepared. The preliminary phytochemical investigation showed the presence of various phytochemical such as total phenolic, flavonoid compounds and tannins. The ethanolic leaves extract of CM (ELECM) and water leaves extract of CM (WLECM), showed dose dependent increased in free radical scavenging activity in DPPH assay and reducing power assay in present study. Moreover, ethanolic barks extract of CM (EBECM) and water barks extract of CM (WBECM), also showed increased in free radical scavenging activity in DPPH assay and reducing power assay. However, the effects of bark extracts were lower than leaves extracts. In the light of the above consideration, the results of the study revealed that ELECM showed promising antioxidant activity in a dose dependent manner.
