【摘要】 目的研究鹅不食草的化学成分。方法采用硅胶、凝胶等多种色谱方法进行分离纯化。结果分离得到10个化合物,分别鉴定为伪蒲公英甾醇乙酸酯(1)、棕榈酸(2)、木栓酮(3)、短叶老鹳草素(4)、青蒿酸(5)、β-谷甾醇(6)、苯甲酸(7)、胡萝卜苷(8)、猫眼草酚D(9)、3-甲氧基槲皮素(10)。结论化合物5和9为首次从鹅不食草中分离得到。更多还原

【Abstract】 Objective To determine the chemical constituents of Centipeda minima. Methods The constituents were separated and purified by means of silica gel and Sephadex LH-20 column chromatography. Results Ten compounds were isolated and identified as: pseudotaraxasteryl acetate(1), palmitic acid(2), friedelin(3), brevilin(4), artemisic acid(5), β-sitosterol(6), benzoic acid(7), daucosterol(8), chrysosplenol D(9), and 5, 7, 3’, 4’-tetrahydroxy-3-methoxy flavone(10). Conclusion Compound 5 and 9 have been obtained from this plant for the first time.更多还原
