摘要
目的研究壮药三角泡(倒地铃Cardiospermum halicacabum干燥全草)的化学成分。方法通过硅胶、聚酰胺、凝胶等柱色谱及重结晶方法进行分离和纯化,根据理化性质和波谱数据对化合物结构进行鉴定。结果从三角泡正丁醇部位分离13个化合物,分别鉴定为金圣草黄素-7-O-β-D-葡萄糖醛酸苷丁酯(1)、金圣草黄素-7-O-β-D-葡萄糖醛酸苷乙酯(2)、金圣草黄素-7-O-β-D-葡萄糖醛酸苷甲酯(3)、金圣草黄素(4)、芹菜素-7-O-β-D-葡萄糖醛酸苷丁酯(5)、芹菜素-7-O-β-D-葡萄糖醛酸苷乙酯(6)、芹菜素-7-O-β-D-葡萄糖醛酸苷甲酯(7)、芹菜素-7-O-β-D-葡萄糖苷(8)、芹菜素(9)、木犀草素-7-O-β-D-葡萄糖醛酸苷甲酯(10)、木犀草素-7-O-β-D-葡萄糖醛酸苷(11)、木犀草素(12)、槲皮素(13)。结论化合物1~3为新的黄酮类化合物,分别命名为倒地铃苷D、倒地铃苷B和倒地铃苷A;化合物5~8、10、11为首次从该属植物中分离得到。
Objective To study the chemical constituents of Zhuang medicine Cardiospermum halicacabum. Methods The compounds were isolated and purified by silica gel, polyamide gel, and Sephadex LH-20 chromatography. The structures of the compounds were identified on the basis of chemical and spectral methods. Results Thirteen compounds were isolated from the butanol extracts of C. halicacabum and identified as chrysoeriol-7-O-β-D-glucuronide butyl ester(1), chrysoeriol-7-O-β-Dglucuronide ethyl ester(2), chrysoeriol-7-O-β-D-glucuronide methyl ester(3), chrysoeriol(4), apigenin-7-O-β-D-glucuronide butyl ester(5), apigenin-7-O-β-D-glucuronide ethyl ester(6), apigenin-7-O-β-D-glucuronide methyl ester(7), apigenin-7-O-β-Dglucuronide(8), apigenin(9), luteolin-7-O-β-D-glucuronide methyl ester(10), luteolin-7-O-β-D-glucuronide(11), luteolin(12), and quercetin(13). Conclusion Compounds 1, 2, and 3 are new flavonoiels named as cardiosperoside D, cardiosperoside B, and cardiosperoside A. Compounds 5—8, 10, and 11 are isolated from this genus for the first time.
