Abstract :Three known flavonol glycosides, i.e., kaempferol 3,7-O-\( a \)-L-dirhamnopyranoside ({\bfseries 1}), kaempferol 3-O-\( b \)-D-glucopyranosyl-(1\( \ra \)2)-\( a-L-rhamnopyranoside-7-O-\( a \)-L-rhamnopyranoside ({\bfseries 2}) and kaempferol 3-O-\( a \)-L-rhamnopyranoside-7-O-\( b \)-D-glucopyranosyl-(1\( \ra \)2)-\( a \)-L-rhamnopyranoside ({\bfseries 3}), were isolated for the first time from the flowers of {\itshape 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 {\bfseries 1-3} were also prepared ({\bfseries 1a, 2a, 3a}) and identified by NMR and positive FAB mass spectra.Keywords : Consolida armeniaca, flavonol glycosides, acetylated flavonol compounds.
