狭叶米口袋化学成分研究

目的：研究狭叶米口袋Gueldenstaedtia stenophylla Bge．的化学成分。方法：用乙醇提取。硅胶柱色谱技术分离纯化，根据理化性质和光谱数据进行结构鉴定。结果：分离得到了6个化合物，其中5个已鉴定，分别为正十六烷酸（n-Hexadecanioc acid，I），β-谷甾醇（β-Sitosterol，Ⅱ），胡萝卜苷（Daucosterol，III），芹菜素（Apigenin，Ⅳ），D．果糖（D．Fructose,V1）。化合物V为甲基取代的黄烷二醇糖苷类，结构尚在鉴定。结论：5个化合物均为首次从狭叶米口袋植物中提取，其中化合物I和Ⅲ为首次从本属植物中获得。

Studies on the Chemical Constituents of Gueldenstaedtia stenophylla

OBJECTIVE: To study the chemical constituents of Gueldenstaeditia stenophylla. METHODS: The constituents were isolated by alcohol extraction, column chromatography on silica gel. Their structures were elucidated by chemical and spectroscopic methods. RESULTS: Six compounds were obtained, and five of them were identified as n-hexadecanioc acid (I), beta-sitosterol (II), daucosterol (III), apigenin (IV), D-fructose (VI). Compound V was being determined. CONCLUSION: Five compounds are isolated from Gueldenstaedtia stenophylla and compounds I, III are extracted from Gueldenstaedtia Fisch for the first time.
