The content of anthocyanin, cyanidin 3-glucoside(C3G) and the peonidin 3-glucoside(P3G) from 591 rice cultivars and the antioxidative activities of MeOH extract from 8 rice cultivars were evaluated. Among them, C3G content of pigmented rice were ranged from 0 to 451.9 mg in 100 g brown rice, while the P3G contents were in the range from 0 to 42.7 mg in 100 g brown rice. There was no correlation between C3G and P3G content. Total anthocyanin content ranged from 0 to 475.1 mg in 100 g brown rice. The antioxidative activity, the scavenging activity on DPPH (2,2-diphenyl-picryl-hydrazyl) radical of MeOH extracts from rice grain, were different according to cultivars. The activity of blockish purple pericarp rice cultivars was twice stronger than that of white pericarp cultivar.
