Abstract
The antioxidant activity of Xanthosoma violaceum Schott corm extract was assayed through in vitro models such as DPPH, Hydroxyl, Superoxide and ABTS radical cation scavenging and reducing power. The total phenolics and flavonoids methanol extract were found to be 0.37g100-1 and 0.48g100-1 respectively. The methanol extract of Xanthosoma violaceum corm showed potent of in vitro antioxidant activities. The maximum inhibitory concentration (IC50) in all models viz Superoxide, ABTS, DPPH and Hydroxyl radical were found to be 73.84, 36.65, 24.56 and 21.04 µg/ml., respectively at 1mg/ml concentration. The finding of the present study confirmed the presence of total phenolics, flavonoids and possess in vitro antioxidant activity.
