Five monoacylated anthocyanins from Brassica oleracea were isolated and their structures determined to be 3-0-(6-0-acyl-2-0-(β-d-glucopyranosyl)-β-d-glucopyranosyl)-5-0-(β-d-glucopyranosyl)cyanidins, in which the acyl group is p-coumaryl, ferulyl, sinapyl, 4-0-(β-d-glucopyranosyl)-E-p-coumaryl, or 4-0-(β-d-glucopyranosyl)-E-ferulyl.
