A malonylated anthocyanin and flavonols in blue Meconopsis flowers

The structures of the major anthocyanin and two flavonols from the blue flowers of Meconopsis were identified by NMR spectroscopy as being cyanidin 3-O-[(6-O-malonyl-2-O-β-d-xy1opyranosyl)-β-d-glucopyranoside]-7-O-β-d-glucopyranoside, kaempferol 3-O-(6-O-β-d-glucopyranosyl)-β-d-glucopyranoside and k...
