Abstract
Four new acylated cyanidin glycosides were isolated from the purple root peers of Raphanus sativus L. ‘Benikanmi’, along with five known anthocyanins. These pigments were based on cyanidin 3-sophoroside-5-glucoside, and acylated diversely with malonic, p-coumaric, caffeic, and ferulic acids. Two pigments of these four new anthocyanins were determined to be cyanidin 3-O-[2-O-(β-glucopyranosyl)-6-O-(trans-feruloyl)-β-glucopyranoside]-5-O-[6-O-(malonyl)-β-glucopyranoside] and cyanidin 3-[2-(glucosyl)-6-(cis-p-coumaroyl)-glucoside]-5-[6-(malonyl)-glucoside] by chemical and spectroscopic methods. Since two other new pigments were obtained in small quantities, their structures were tentatively assigned to be malonyl cyanidin 3-sophoroside-5-glucoside and malonyl cyanidin 3-[2-(glucosyl)-6-(trans-caffeoyl)-glucoside]-5-glucoside, mainly on the basis of their spectroscopic data. From the results, the potential of these purple root anthocyanins as natural food colorants is discussed.
