摘　　要：目的:对尾叶紫金牛的化学成分进行研究。方法:应用正相硅胶、Sephadex LH-20、MCI gel、ODS等填料进行分离纯化,运用MS、1H-NMR、13C-NMR结合理化性质鉴定结构。结果:从尾叶紫金牛的乙酸乙酯萃取部位及正丁醇萃取部位共分离鉴定了5个化合物,分别为射干醌G(Ⅰ),5-(顺-8-十七碳烯基)间苯二酚(Ⅱ),射干醌H(Ⅲ),山奈酚-3-O-α-L-鼠李糖苷(Ⅳ),槲皮素-3-O-α-L-鼠李糖苷(Ⅴ)。结论:所有化合物均为首次从该植物中分离得到。Objective: To study the chemical constituents from Ardisia caudata Hemsl.Method: The normal phase silica gel,Sephadex LH-20,MCI gel and ODS packing material were used to isolate and purify the chemical constituents.The structures were identified by the methods of MS,1H-NMR,13C-NMR combined with physicochemical property.Result: Five compounds extracted from the ethyl acetate extraction parts and the butyl alcohol extraction parts of Ardisia caudata Hemsl.were identified as belamcandaquinone G(Ⅰ),5-(Z-heptadec-8-enyl) resorcinol(Ⅱ),belamcandaquinone H(Ⅲ),kaempferol-3-O-αL-rhamnopyranoside(Ⅳ),quercetin-3-O-α-L-rhamnopyranoside(Ⅴ).Conclusion: All the compounds are isolated from Ardisia caudata Hemsl.for the first time.
