  • This study evaluates the antioxidant capacity of 40 varieties of colored barley and hulled barley. For investigation of the antioxidant capacity as well as the contents of anthocyanin, color intensity, total phenolic acids contents, SOD-like activity, samples were extracted in ethanol with 0.1$\%$ TFA. The content of anthocyanin was measured spectrophotometrically. The total phenolic acid content was analyzed by using th Folin-Ciocalteu method, and the color intensity was determined by using the color difference meter. The results showed that in the anthocyanin content and color intensity of colored barley there were significant differences according to their varieties. The resulting concentration levels were divided into three groups: Group I (high) Group II (medium), and Group III (low). In the measurements of antioxidant capacity significant differences(P < 0.05) were found among varieties in those groups. Colored barley was higher in electrondonating capability, SOD-like activity, iuhibitory effects on lecithin oxidation, and hydrogen radical- scavenging ability Meanwhile, from different antioxidant tests, No. 26, 27, 34, and 35 varieties measured high in antioxidation ability fell into Group I high in the anthocyanin content. This results suggest that the anthocyanin content has a significant relationship on antioxidant activity.
