Abstract

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)-beta-D-glucopyranoside]-7-O- [6-O-(4-O-(6-O-(p-hydroxybenzoyl)-beta-D-glucopyranosyl)-p-hydroxybenzoy l)- beta-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)-beta-D-glucopyranoside]-7-O-[2-O-(beta-D- glucopyranosyl)-6-O-(4-O-(6-O-(p-hydroxybenzoyl)-beta-D-glucopyranosyl)- p- hydroxybenzoyl)-beta-D-glucopyranoside]. The third pigment was elucidated to be delphinidin 3-O-[6-O-(malonyl)-beta-D-glucopyranoside]-7-O-[2-O-(6-O-(p- hydroxybenzoyl)-beta-D-glucopyranosyl)-6-O-(4-O-(6-O-(p-hydroxybenzoyl)- beta-D- glucopyranosyl)-p-hydroxybenzoyl)-beta-D-glucopyranoside], and the fourth as delphinidin 3-O-[6-O-(malonyl)-beta-D-glucopyranoside]-7- O-glucopyranosyl[(2-O-(6-O-(p-hydroxybenzoyl)-beta-D-glucopyranosyl)-6-O - (4-O-(6-O-(p-hydroxybenzoyl)-beta-D-glucopyranosyl)-p-hydroxybenzoyl)-be ta-D- glucopyranoside].
