Abstract:

The antioxidant activity of extracts from bulbil of Dioscorea opposita was assessed by determining their reducing abilities and scavenging abilities on hydroxyl radical (·OH), superoxide anion radical (O2·) and 1,1-diphenyl-2-picrylhydrazyl radical (DPPH·). The results showed that the extracts from bulbil of Dioscorea opposita have significant antioxidant activity in vitro.

Key words: Dioscorea opposita, bulbil, antioxidant activity
