[A novel isoflavone glycoside from Caragana alaica].
3-O-Rhamnopyranosylisorhamnetin, 3-O-glucopyranosylisorhamnetin, 7-O-galactopyranosylluteolin, quercitrin isoquercitrin, wistin, and a novel isoflavonoid, 3'-hydroxy-6,4'-dimethoxy-7-O-beta-D-glucopyranosylisoflavone, were isolated from the aerial parts of Caragana alaica. Of these, the previously described compounds were identified on the basis of their physicochemical and spectral characteristics, whereas the spectral analysis and conversion to a known compound, cladrastin, allowed the structural elucidation of the novel isoflavone glycoside.
