摘要: 从苦碟子(Ixeris sonchifolia Hance)的全草中分得5 个黄酮, 分别为木犀草素-7-O-β-D-葡萄糖醛酸苷甲酯(1), 芹菜素-7-O-β-D-葡萄糖醛酸苷甲酯(2), 木犀草素(3), 木犀草素-7-O-β-D-葡萄糖苷(4),芹菜素(5)。它们的结构经各种光谱解析确定, 其中化合物1 2 为新黄酮。

关键词: 苦碟子, 黄酮, 木犀草素-7-O-β-D-葡萄糖醛酸苷甲酯, 芹菜素-7-O-β-D-葡萄糖醛酸苷甲酯

Abstract: From the whole plants of Ixeris conchifolia Hance, two novel flavonoids, named luteolin-7-O-β-D- glucuronide methyl ester (1) and apigenin-7-O-β-D-glucuronide methyl ester (2), together with three known flavonoids luteolin (3), luteolin 7-glucoside (4) and apigenin (5) were isolated and their structures were elucidated on the basis of spectral data.
