Abstract
Three anthocyanins were isolated from the acidified methanol extracts of UI 911 black beans (Phaseolus vulgaris L.) using solid phase extrac tion and preparative high-performance liquid chromatography. The antho cyanins were characterized using chromatographic and spectroscopic met hods as delphinidin 3-glucoside (56%), petunidin 3-glucoside (26%), an d malvidin 3-glucoside (18%). The monomeric anthocyanin content was 21 3 +/- 2 mg/100g of black beans (moisture content was 10.04 +/- 0.02%).
