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