Structures of common anthocyanins. An example of nonacylated and acylated anthocyanins. Glucose is attached to the C3 position of anthocyanidin (A) to form nonacylated anthocyanin (B). Based on nonacylated anthocyanin, p-coumaric acid is acylated with a glucose residue at the C6 position to form acylated anthocyanin (C). Malvidin-3-O-glucoside (D). Petunidin-3-O-[6-O-(4-O-E-p-coumaroyl-O-α-l-rhamnopyranosyl)-β-d-glucopyranoside]-5-O-β-d-glucopyranoside (E), adapted with permission from ref (105). Copyright 2003 Elsevier.
