Abstract:
Objective: To evaluate the total phenolic, flavonoid contents and in vitro antioxidant activity of methanol extract of Xanthosoma sagittifolium corm. Methods: Total phenolic content was estimated using the Folin Ciocalteu method. The flavonoid content was determined using aluminium chloride. In vitro antioxidant activities were evaluated by studying DPPH radical scavenging activity, hydroxyl radical scavenging activity, superoxide radical scavenging activity, ABTS radical cation scavenging activity and reducing power capacity were determined using standard procedure. Results:Xanthosoma sagittifolium corm exhibited 0.32g100g-1 total phenolic; 0.26g100g-1 flavonoid and better scavenging activity of DPPH (78.22±0.56%), hydroxyl radical (69.11±0.21%), superoxide radical (83.27±0.08%) and ABTS radical cations(76.11±0.07%).Conclusions: The present studies confirm the methanol extracts have potential in vitro antioxidant activity.
