Abstract

The antioxidative constituents isolated from Hedyotis diffusa were identified as quercetin 3-O-${\beta}$-rutinoside (1) and quercetin 3-O-${\beta}$-glucoside (2). We also isolated asperuloside (3) from this plant. Identification was done based on spectroscopic analysis. Quercetin 3-O-${\beta}$-rutinoside was the stronger antioxidant than quercetin 3-O-${\beta}$-glycoside while asperuloside was inactive.
