In fresh leaves of Acanthopanax sciadophylloides FR. et SAV. collected in June, the following substances were identified : (-)-β-caryophyllene, trans-β-farnesene, phytol, 1-dotriacontanol, taraxerol, a mixture of stigmasterol and β-sitosterol, trans-p-coumaric acid, trans-p-coumaric acid methylester, afzerin, kaemferitrin, kaempferol 7-O-α-L-rhamnopyranoside, 3-O-β-D-galactopyranosyl kaempferol 7-O-α-L-rhamnopyranoside and quercetin 3, 7-O-bis-α-L-rhamnopyranoside. On the other hand, from the fresh leaves collected in August, trans-p-coumaric acid and kaempferol were obtained as aromatic compounds, but flavonoid glycosides were not detected. It is interesting that the constituents of these leaves were quite different between June and August.
