GLYCOSIDES OF PHENOLIC ACID AND FLAVONOIDS FROM THE LEAVES OF GLYCYRRHIZA URALENSIS FISCH

Seven glycosidic constituents have been isolated from the dried leaves of Glycyrrhiza uralensis Ficsh. (Leguminosae). The Structures of these compounds havefor identified as 1-O-protocatechuyl-β-D-xylose (Ⅰ), apigenin-6, 8-di-C-β-D-glucopyranoside (vicenin-2, Ⅱ), isorhamnetin-3-O-rutinoside (narcissin,Ⅲ) kaempferol-3-O-rutinoside (nicotiflorin Ⅳ), kaempferol-3-O-β-D-glucopyranoside (astragalin, Ⅴ), quercetin-3-O-rutinoside (rutin, Ⅵ), and quercetin-3-O-β-D-glucopyranoside (isoquercitrin, Ⅶ) by chemical method and spectroscopicanalysis. Among these compounds, Ⅰis a new compound, named uralenneoside; Ⅲwas reported for the first time in the genus; Ⅲ to Ⅶ were isolated for the first time fromthe species. Ⅱ to Ⅶ are known biologically active constituents.
