ABSTRACT
Antioxidant activity of rhizome of Nymphaea pubescens was studied for its free radical scavenging property on different in vitro models viz, DPPH, hydroxyl, superoxide, ABTS and reducing power by using methanol extract. Total phenolic and flavonoid contents were estimated. In vitro antioxidant activity revealed that the methanol extract showed more potent activity. In vitro antioxidant activity was compared with standard ascorbic acid/ trolox.
