The methanolic extract of the leaves of Sambucus Sieboldiana BLUME. was examined and sucrose (I), methyl chlorogenate (III), kaempferol (IV), and quercetin (V) were isolated together with a flavonoid compound (VI). The structure of compound (VI), which was hydrolyzed to each mole of D-galactose, D-glucose, and kaempferol, was proved to be kaempferol-3-O-bioside by complete methylation followed by hydrolysis to 4', 5, 7-tri (O-methyl) kaempferol. By comparison of the Rf of PPC and thin -layer chromatography (TLC), and of ultraviolet (UV) and infrared (IR) spectrum, compound (VI) was identified with panasenoside (kaempferol 3-O-glucogalactoside), isolated from the herb of Panax ginseng C.A.
