摘要：

The structures of the two major anthucyanins in blue Agapanthus flowers have been determined to be a p-coumaroylated delphinidin diglycoside attached to a flavonol triglycoside via a succinic acid diester link. The structure has been determined unambiguously through degradation studies, glycosidic analysis and NMR experiments. These compounds represent unique examples of anthocyanin pigments where both types of co-pigment, an aromatic acyl group and a flavonoid co-pigment, are attached covalently to the anthocyanin.
