摘　　要：前文曾报道从中药槲寄生Viscum coloratum(Kom.)Nakai中分得黄酮、三萜和有机酸等化合物。现又从槲寄生的乙醇提取物中,经大孔吸附树脂层析和反复硅胶柱层析分得化合物Ⅷ～Ⅺ,经波谱分析和水解试验,确定Ⅷ的结构为2,3-丁二醇单葡萄糖甙;Ⅸ的结构为紫丁香甙;Ⅹ的结构为五加甙E;Ⅺ的结构为紫丁香甙元-O-β-D-芹糖基(1→2)葡萄糖甙。Ⅷ为一新结构的醇甙。From the ethanol extract of V/iscum coloratum (Kom.) Nakai , a giucoside ofaliphatic diol and three other glucosides were isolated. Based on chemical and spectroscopic analysis,the structures have been elucidated as 2-β-D- glucosyl-3- methylpropanol (Ⅷ), syringin (Ⅸ),eleatheroside E(Ⅹ) and syringenin-4'-O-D-apiosylglucoside (Ⅺ). Ⅷ is a new glucoside of aliphaticdiol and named 3-β-D-glucopyranosyloxy-butanol-2. Three other compounds (Ⅸ～-Ⅺ) were foundfor the first time in this plant.
