目的:研究绵参Eriophyton wallichii的化学成分。方法:以甲醇提取,硅胶及ODS柱色谱分离,采用MS和NMR等方法鉴定化合物的结构。结果:分离鉴定了7个化合物,分别为β-谷甾醇(1),夏至草苦素(marrubi-in,2),乌苏酸(3),cimigoside(4),5-deoxyantirrhinoside(5),8-表马钱子酸葡萄糖苷(8-epiloganic acid,6)和apigenin7-(6″-p-coumaroyl)glucoside(7)。结论:以上化合物均为首次从该植物中分离得到。
Objective: To study the chemical constituents ofEriophyton wallichii. Method: The constituents were isolated and purified by silica gel column and Sephadex LH-20 chromatography. Their structures are elucidated by physicochemical properties and spectral analysis. Result: Seven compounds were obtained and identified as β-sitosterol (1) ,marrubiin (2), ursolic acid (3), cimigoside (4), 5-deoxyantirrhinoside (5), 8-epiloganic acid (6) and apigenin 7 - ( 6''-p -coumaroyl) glucoside ( 7 ). Conclusion: Compounds 1-7 were isolated from this plant for the first time.
