Abstract

Two novel polyacylated cyanidin glycosides were isolated from the purple-red flowers of Anemone coronaria 'St. Brigid' together with a known polyacylated cyanidin glycoside (Anemone Purple Anthocyanin 1). These novel pigments were identified as cyanidin 3-O-[2-O-(2-O-(transcaffeoyl)-β-D-glucopyranosyl)-6-O-malonyl-β-D-galactopyranoside]-7-O-[6-O-(trans-caffeoyl)-β-D-glucopyranoside]-3'-O-β-D-glucuronopyranoside and its demalonyl derivative.
