Abstract

Three novel flavonoid glycosides, 5,6-dimethyoxy-3′,4″- dioxymethylene-7-O-(6″-β-D-glucopyranosyl-β-D-glucopyranosyl) flavanone (1), 5,4′-dihydroxy-3-O-α-L-rhamnopyranosyl-6-C- glucopyranosyl-7-O-(6″-para-coumaroyl-β-D-glucopyranosyl) flavone (2) and 5,4′-dihydroxy-3-O-(2″‴-β-glucopyranosyl-α- L-rhamnopyranosyl)-6-C-glucopyranosyl-7-O-(6″-para-coumaroyl-β- D-glucopyranosyl) flavone (3) were isolated from the 1-butanol soluble fraction of the bulbs of the plant Urginea indica (Indian squill). The structures of the compounds were elucidated on the basis of spectral analysis, including homo- and heteronuclear correlation NMR experiments (COSY, NOESY, HSQC and HMBC) and mass spectra.
