狭叶米口袋化学成分研究

Studies on the Chemical Constituents of Gueldenstaedtia stenophylla

目的:研究狭叶米口袋Gueldenstaedtia stenophyllaBge.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,Ⅵ)。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。

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 ）, β-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.
