| Abstract: | Five polyacylated anthocyanins were isolated from blue-violet flowers of Anemone coronaria 'St. Brigid'. They were identified as delphinidin 3-O-2-O-(2-O-(trans-caffeoyl)-beta-D-glucopyranosyl)-6-O-(malonyl)-beta-D-galactopyranoside]-7-O-6-O-(trans-caffeoyl)-beta-D-glucopyranoside]-3'-O-beta-D-glucuronopyranoside], and its demalonylated form, delphinidin 3-O-2-O-(2-O-(trans-caffeoyl)-beta-D-glucopyranosyl)-6-O-(2-O-tartaryl)malonyl)-beta-D-galactopyranoside]-7-O-6-O-(trans-caffeoyl)-beta-D-glucopyranoside]-3'-O-beta-D-glucuronopyranoside], and its cyanidin analog as well as delphinidin 3-O-2-O-(2-O-(trans-caffeoyl)-beta-D-glucopyranosyl)-6-O-(2-O-(tartaryl)malonyl)-beta-D-galactopyranoside]-7-O-6-O-(trans-caffeoyl)-beta-D-glucopyranoside]. |
