摘要
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,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.
Abstract
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-hexadeeanioc acid( Ⅰ ), β-sitosterol(Ⅱ ), daucosterol ( Ⅲ) ,apigenin( Ⅳ) ,D-fructose( Ⅵ). Compound Ⅴ was being determined. Conclusion: Five compounds are isolated from Guelden staedtia stenophylla and compounds Ⅰ ,Ⅲ are extracted from Gueldenstaedtia Fisch for the first time.
