Abstract

Three known flavonol glycosides, i.e., kaempferol 3,7-O-alpha-L-dirhamnopyranoside (1), kaempferol 3-O-beta-D-glucopyranosyl-(1-->2)-alpha-L-rhamnopyranoside (2) and kaempferol 3-O-alpha-L-rhamnopyranoside-7-O-beta-D-glucopyranosyl-(1-->2)-alpha-L-rhamnopyranoside (3), were isolated for the first time from the flowers of Consolida armeniaca, and the structures of flavonol glycosides were deduced by high field 1D and 2D NMR and FAB-MS spectroscopies. The acetyl derivatives of 1-3 were also prepared (1a, 2a, 3a) and identified by NMR and positive FAB mass spectra.
