短柱肖菝葜化学成分的研究

Studies on Chemical Constituents of Heterosmilax yunnanensis

目的:对短柱肖菝葜的化学成分进行研究。方法:应用多种色谱技术进行分离纯化,通过理化方法和波谱数据进行结构鉴定。结果:从95%乙醇提取物中脂溶性部位分离并鉴定了8个化合物,分别为β-谷甾醇(Ⅰ),单棕榈酸甘油酯(Ⅱ),胡萝卜苷(Ⅲ),二十六烷酸(Ⅳ),5-羟甲基糠醛(Ⅴ),佛手内酯(Ⅵ),熊果酸(Ⅶ),甘草素(Ⅷ)。结论:这些化合物均系首次从该植物中分离得到。其中,化合物Ⅳ～Ⅷ为首次从该属植物中分离得到。

Objective：To study the chemical constituents of Heterosmilax yunnanensis. Methods：The compounds were isolated and repeatedly purified with chromatograph and the structures were elucidated by physieo-chemical properties and spectral analysis. Results： Eight compounds were obtained and elucidated as β-sitosterol（ I ）, glycerol monopalmitate （ II ） ,daucosterol （Ⅲ ）, hexacosanoic acid （ IV ） ,5-hydroxymethyl furaldehyde （ V ） , bergapen （ Vt ） , ursolic acid （Ⅶ） , liquiritigenin （ Ⅷ ）. Conclusion：They have been isolated from this plant for the first time, and IV -Ⅷ are obtained from the plants of Heterosmilax for the first time.
