Abstract

Black red color of Aduki beans is manifested by a pigment belonging to the anthocyanin group. This was isolated and purified in the form of crystalline picrate. By a series of paper chromatographic analyses, the pigment was identified as 3-monoglucoside of delphinidin. This is quite interesting in view of the previous finding that chrysanthemin, a derivative of cyanidin having the same glycosidic pattern, is responsible for the same color in the seed coat of black soy bean.
