In the previous paper, it was reported that kaempferitrin, antoside, myoinositol and scyllitol were isolated from the leaves of Acanthopanax sciadophylloides and the constituents were different according to the districts where the materials came from. By further investigation, kaempferol 7-rhamnoside and quercetin 7-rhamnoside were isolated and the differences of the constituents were found to be quantitative ; in some cases, some of these compounds were detected only by paper chromatography as shown in Table I. The benzene extract of the leaves was examined by column chromatography. Hydrocarbons, dotriacontanol, 2-nonacosanone, taraxerol and a new compound, mp 184°, were isolated. The gas chromatogram of the hydrocarbons (Fig. 2) showed that the main component was nonacosane (77%) accompanied by heptacosane (1%), octacosane (4%), triacontane (8%), and hentriacontane (10%). It was concluded that hirsutrin was identical with isoquercitrin (quercetin 3-β-D-glucoside).
