Dried leaves of Acanthopanax sciadophylloides FRANCH. et SAV. were extracted with methanol and the water-soluble part of the extract was treated successively with solutions of lead acetate, basic lead acetate, and ammoniacal alkaline lead salt, as shown in Chart 1. myo-inositol, scyllitol, kaempferitrin, and antoside were isolated and identified. The constituents of these leaves were somewhat different according to the district where the materials came from. Utkin had suggested the structure of antoside as quercetin 3 (7)-glucosido-7 (3)-rhamnoside. Relative positions of glucose and rhamnose in the antoside molecule were now determined by enzymatic cleavage of rhamnose to give quercetin 3-glucoside (isoquercitrin) (Chart 2).
