[Flavoneglycosides in the flowers of Paeonia arborea and P. suffruticosa].

Three glycosides have been isolated fromPaeonia arborea: kaempferol-3-β-glucoside-7-β-glucoside (Paeonoside), apigenin-7-β-glucoside, and apigenin-7-rhamnoglucoside (Rhoifolin).Paeonia suffruticosa also contains these three compounds but its main glycoside is kaempferol-3-β-glucoside (astragalin), which is present inPaeonia arborea only in traces.
