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.
