Flavonoids from some species of genus Scopolia Jacq.
Kaempferol 3-O-(2-glucosyl)-galactoside-7-O-glucoside was isolated from the leaves of Scopolia carniolica Jacq. and S. sinensis Hemsl. From the latter taxon as well as kaempferol 3-O-galactoside and 3-O-(2-glucosyl)-galactoside, kaempferol and quercetin 3-O-robinobiosides and quercetin 3-O-sophoroside have been obtained. Moreover, from the leaves of S lurida Dun. kaempferol and quercetin 3-O-glucosides and 3-O-rutinosides were isolated. The structures of compounds have been determined by means of chemical and spectral methods (UV, LSI MS, 1H and 13C NMR, 1H-1H COSY NMR).[1]References
