Abstract Two new flavonoids,named luteolin-7-O-β-D-glucuronide methyl ester and apigenin-7-O-β-D-glucuronide methyl ester,were isolated from the whole plant of Ixeris sonchifolia(Bge.)Hance.Their structures were deduced and confirmed by the chemical method and spectoscopic analysis(1H-NMR,13C-NMR).

苦碟子为菊科植物抱茎苦荬菜[Ixeris sonchifolia(Bge.)Hance]的当年生干燥全草.具有清热解毒、排脓之功效.利用大孔树脂、硅胶柱层析及聚酰胺柱层析从中分离得到两个新的黄酮苷类成分,其中一个命名为木犀草素-7-O-β-D-吡喃葡萄糖醛酸苷甲酯(luteolin-7-O-β-D-glucuronide methyl ester,Ⅰ),另一个为芹菜素-7-O-β-D-吡喃葡萄糖醛酸苷甲酯(apigenin-7-O-β-D-glucuronide methyl ester,Ⅱ).这两种成分是首次从本属植物中得到.
化合物(Ⅰ)为黄色针状结晶,盐酸-镁粉反应阳性,Molish反应阳性,酸水解检出葡萄糖醛酸.通过各种谱学的分析〔1~3〕(1H-NMR,13C-NMR)并与已知物木犀草素-7-O-β-D-吡喃葡萄糖醛酸苷相对照确定了其结构.其氢谱、碳谱数据见表1.
