摘要
目的研究菊科植物祁州漏芦Rhaponticum uniflorum根的化学成分。方法采用系统溶剂提取法结合各种色谱分离技术、理化性质和光谱数据鉴定结构。结果从祁州漏芦根里分离得到11个单体成分,其中6个噻吩类,2个甾醇类,1个五环三萜类,2个长链脂肪酸类。结构鉴定为牛蒡子醛(arctinal,1)、牛蒡子酮-b(arctinone-b,2)、7-chloroarctinone b(3)、5-methoxyl-5′-(1-propinyl)-2,2′-dithiophene(4)、β-谷甾醇(β-sitosterol,5)、豆甾醇(stig-masterol,6)、齐墩果酸(oleanolic acid,7)、棕榈酸(pal mitic acid,8)、E-7,9-diene-11-methenyl pal mitic acid(9)、5-me-thoxyl-2,2′-dithiophene(10)和5-(4-acetoxyl-1-butynyl)-2,2′-dithiophene(11)。结论化合物4和8-11是首次从该属植物中分离得到。
Objective To study the chemical constituents in the root of Rhaponticum uniflorum.Methods Separation and purification were performed on silica gel and prep-TLC.Their structures were elucidated on the basis of physicochemical and spectral analyses.Results Eleven compounds were isolated and identified as arctinal(1),arctinone-b(2),7-chloroarctinone b(3),5-methoxyl-5′-(1-propinyl)-2,2′-dithiophene(4),β-sitosterol(5),stigmasterol(6),oleanolic acid(7),palmitic acid(8),E-7,9-diene-11-methenyl palmitic acid(9),5-methoxyl-2,2′-dithiophene(10),and 5-(4-acetoxyl-1-butynyl)-2,2′-dithiophene(11),respectively.Conclusion Compounds 4,8-11 are isolated from the plants of Rhaponticum Cass.for the first time.
