摘　　要：目的:研究峨眉紫金牛石油醚萃取部位的化学成分。方法:应用硅胶、Sephadex LH-20等柱色谱技术进行分离纯化,运用波谱学方法结合理化性质鉴定结构。结果:从峨眉紫金牛的石油醚萃取部位共分离得到5个化合物,经鉴定分别为棕榈酸,谷甾醇,菠甾醇,紫金牛素E,3-[(Z)-13-十七碳烯基]-2-羟基-5-甲氧基-对苯醌。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 the petroleum ether extraction parts of Ardisia caudata Hemsl. Method: The silica gel and Sephadex LH-20 was used to isolate and purify the chemical constituents. And their structures were identified by the spectroscopic methods combined with physicochemical property. Result: Five compounds extracted from the PE extraction parts of Ardisia caudata Hemsl. were identified as palmitic acid, sitosterol, spinasterol, Ardisin E, 3-[(Z)-13-heptadecenyll-2-hydroxy-5-methoxy-p-benzoquinone. Conclusion: All compounds were isolated from Ardisia caudata Hemsl. for the first time.
