【摘要】 目的研究东北铁线莲Clematis manshurica的化学成分。方法利用硅胶、Sephadex LH-20、PHPLC等色谱方法进行化合物的分离纯化,根据化合物的理化性质、光谱数据进行结构鉴定。结果分离得到11个化合物,分别鉴定为角鲨烯(Ⅰ)、木栓酮(Ⅱ)、正二十六烷酸(Ⅲ)、β-谷甾醇(Ⅳ)、豆甾醇(Ⅴ)、齐墩果酸(Ⅵ)、β-胡萝卜苷(Ⅶ)、5-羟甲基糠醛(Ⅷ)、丹参素甲酯(Ⅸ)、5R-5-羟甲基-2(3H)-呋喃酮(Ⅹ)、5R-5-羟甲基-2(5H)-呋喃酮(Ⅺ)。结论 11个化合物除β-谷甾醇外均为首次从东北铁线莲中分离得到。更多还原

【Abstract】 Objective To study the chemical constituents of Clematis manshurica. MethodsThe extract from the roots and rhizomes of C. manshurica was subjected to chromatography on silica gel and Sephadex LH-20 column. The compounds obtained were identified on the basis of their physicochemical and spectroscopic evidences. ResultsEleven compounds were isolated and their structures were elucidated as squalene (Ⅰ), friedelin (Ⅱ), hexacosoic acid (Ⅲ), β-sitosterol (Ⅳ), stigmasterol (Ⅴ), oleanolic acid (Ⅵ), β-daucosterol (Ⅶ), 5-hydroxymethyl-2-furaldehyde (Ⅷ), methyl 3, 4-dihydroxy-phenyl lactate (Ⅸ), 5R-dihydro-5-hydroxymethyl-2(3H)-furanone (Ⅹ), 5R-5-hydroxymethyl-2(5H)-furanone (Ⅺ). ConclusionAll the compounds except for β-sitosterol are isolated from the plant for the first time.更多还原
