摘要
目的:分离与鉴定牛蒡子中的化学成分。方法:采用硅胶柱色谱、SephadexLH-20等手段对牛蒡子进行分离纯化,通过理化性质鉴别与各种波谱学方法鉴定其结构。结果:从牛蒡子中分离鉴定出10个化学成分,分别为β-谷甾醇(1)、牛蒡子苷元(2)、罗汉松脂素(3)、牛蒡酚B(4)、牛蒡酚A(5)、牛蒡酚F(6)、牛蒡子苷(7)、8-hydroxypinoresino(l8)、(+)-Fraxiresino(l9)、胡萝卜苷(10)。其中,化合物8、9为首次从牛蒡子中获得。结论:本试验结果可为牛蒡子的进一步研究提供依据。
OBJECTIVE:To separate and identify chemical constituents in the seeds of Arctium lappa.METHODS:Compounds were isolated with silica gel and Sephadex LH-20 gel column chromatography,and its structures were identified on the basis of physiochemical property and spectral analysis.RESULTS:10 compounds were isolated and identified as β-sitosterol(1),arctigenin(2),matairesinol(3),lappaol B(4),lappaol A(5),lappaol F(6),arctiin(7),8-hydroxypinoresinol(8),(+)-Fraxiresinol(9)and daucosterol(10).Compound 8,9 were obtained form the seeds of A.lappa for the first time.CONCLUSION:The study provides reference for further study of A.lappa.
