Four new acylated delphinidin 3,7-glycosides were isolated from the blue-violet flowers of Consolida armeniaca as major anthocyanin pigments. The first pigment was based on delphinidin 3,7-diglucoside and was identified as delphinidin 3-O-[6-O-(malonyl)-β-D-glucopyranoside]-7-O-[6-O-(4-O-(6-O-(p- hydroxybenzoyl)-β-D-glucopyranosyl)-p-hydroxybenzoyl)-β-D- glucopyranoside] by spectral methods. The other three acylated anthocyanins were based on delphinidin 3-glucoside-7-sophoroside. The second pigment was determined to be delphinidin 3-O-[6-O-(malonyl)-β-D-glucopyranoside]-7-O-[2-O-(β-D-glucopyranosyl)- 6-O-(4-O-(6-O-(p-hydroxybenzoyl)-β-D-glucopyranosyl)-p-hydroxybenzoyl)- β-D-glucopyranoside]. The third pigment was elucidated to be delphinidin 3-O-[6-O-(malonyl)-β-D-glucopyranoside]-7-O-[2-O-(6-O-(p-hydroxybenzoyl)- β-D-glucopyranosyl)-6-O-(4-O-(6-O-(p-hydroxybenzoyl)-β-D- glucopyranosyl)-p-hydroxybenzoyl)-β-D-glucopyranoside], and the fourth as delphinidin 3-O-[6-O-(malonyl)-O-D-glucopyranoside]-7-O-glucopyranosyl[(2-O-(6-O-(p- hydroxybenzoyl)-β-D-glucopyranosyl)-6-O-(4-O-(6-O-(p-hydroxybenzoyl)- β-D-glucopyranosyl)-p-hydroxybenzoyl)-β-D-glucopyranoside].
