摘要:

利用大孔树脂、MCI柱色谱、凝胶柱色谱和制备液相等对绵萆薢化学成分进行研究。通过1H-NMR、13C-NMR、ESI-MS等波谱方法鉴定分离得到的化合物结构,从绵萆薢中分离得到10个化合物,分别鉴定为3个芳香族化合物:diosniponol C(1)、3,5-dihydroxy-4,4'-dimethoxybibenzyl(9)、覆盆子酮(10);2个皂苷类化合物:甲基原薯蓣皂苷(2)、原纤细薯蓣皂苷(6);3个二芳基庚烷类化合物:(3R,5R)-3,5-dihydroxy-1,7-bis -(4-hydroxy-3-methoxyphenyl)-heptane 3-O-β-D-glucopyranoside(3)、(3R,5R)-3,5-dihydroxy-1,7-bis(4-hydroxyphenyl)heptane 3-O-β-D-glucopyranoside(4)、(3R,5R)-3,5-dihydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)heptane 3-β-D-glucopyranoside(5);1个生物碱类化合物cyclo(l-Pro-l-Leu)(7);1个甾醇类化合物:β-谷甾醇(8),其中化合物(3~5)、(7)、(9)为首次从绵萆薢药材中分离得到。本研究对绵萆薢70%乙醇提取物化学成分进行系统性分离,丰富了绵萆薢化学成分组成,为绵萆薢的综合开发利用奠定基础。

Abstract:

The chemical compositions of Dioscorea spongiosa were investigated using macroporous resin, MCI column chromatography, gel column chromatography and preparative liquid chromatography. The structures of the isolated compounds were identified by 1H-NMR, 13C-NMR, ESI-MS. Ten compounds were isolated from Dioscorea spongiosa, which were identified as three aromatic compounds: diosniponol C (1), 3,5-dihydroxy-4,4'-dimethoxybibenzyl (9), P-hydroxyphenyl butanone (10);two saponin analogues: methyl protodioscin (2), protogracillin (6); three diarylheptanoids: (3R,5R)-3,5-dihydroxy-1,7-bis-(4-hydroxy-3-methoxyphenyl)-heptane 3-O-β-D-glucopyranoside (3), (3R,5R)-3,5-dihydroxy-1,7-bis(4-hydroxyphenyl)heptane 3-O-β-D-glucopyranoside (4), (3R,5R)-3,5-dihydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)heptane 3-β-D-glucopyranoside (5); one alkaloid: cyclo(l-Pro-l-Leu)(7); one sterols: β-sitosterol(8), of which compounds (3~5),(7),(9) were isolated from Dioscorea spongiosa for the first time. In this study, the chemical constituents of 70% ethanol extract of Dioscorea spongiosa were systematically isolated, which enriched the chemical composition and laid the foundation for the comprehensive development of Dioscorea spongiosa.

Key words: Dioscorea spongiosa, chemical constituents, structural identification
