Two new flavone glycosides with an unusual interglycosidic linkage have been isolated from the petals of Salvia uliginosa and identified by NMR spectroscopy as apigenin 7-O-β-D-glucopyranosyl-(1''' → 4'')-β-D- glucopyranoside and apigenin 7-O-β-D-glucopyranosyl-(1''' → 4'')-β-D- glucopyranoside-4'-O-β-D-glucopyranoside. The NMR and UV spectra of these compounds were compared with those of the known compound, apigenin 7,4'-O,O- di-β-D-glucopyranoside, which was isolated from the same source.
Lamiaceae, apigenin 7, 4'-O, O- diglucoside, apigenin 7-O- cellobioside, apigenin 7-O-cellobioside-4'-O-glucoside, copigment, petals, Salvia uliginosa
