Abstract
Eight acylated anthocyanins were isolated from the storage roots of the pur ple sweet potato, Ipomoea batatas cv Yamagawamurasaki, which is the source of the food colorant "purple sweet potato color." Of these, six pigments we re identified as diacylated anthocyanins, cyanidin and peonidin 3-O-(6-O-(E )-caffeyl-2-O-(6-O-acyl-beta-D-glucopyranosyl)-beta-D-glucopyranoside)-5-O- beta-D-glucopyranosides, in which each acyl subsutituent was a p-hydroxyben zoyl, (E)-caffeyl or (E)-ferulyl residue, mainly by NMR analyses.
