【摘要】 七叶一枝花(Paris polyphylla Smith),百合科(liliaceous)重楼属(Paris)植物。该植物具有清热解毒、消肿止痛、凉肝定惊之功效,近年来诸多药理实验研究表明该植物具有止血、抗肿瘤、抗生育、免疫调节及心血管等多方面的生理活性。因此,充分开发和利用这一丰富的自然资源有着十分重要的意义。 本课题针对中药七叶一枝花的活性成分进行了系统的提取分离和结构研究。我们采用传统与现代技术相结合的方法,在实验中使用硅胶柱层析、大孔吸附树脂层析、葡聚糖凝胶层析和反相硅胶柱层析、薄层层析和重结晶等分离方法,从七叶一枝花根茎部分共提取分离得到6个纯净化合物,经波谱分析和化学方法确定它们分别为:CH3(CH2)14COOH(A)、C57H104O6(B)、25R-薯蓣皂苷元-α-L-鼠李吡喃糖基-(1→2)-α-L-阿拉伯呋喃糖基-(1→4)-β-D-葡萄吡喃糖苷(C)、25R-薯蓣皂苷元-α-L-鼠李吡喃糖基-(1→4)-α-L-鼠李吡喃糖基-(1→4)-[α-L-鼠李吡喃糖基-(1→2)]-β-D-葡萄吡喃糖苷(D)、25R-偏诺皂苷元-α-L-鼠李吡喃糖基-(1→2)-α-L-阿拉伯呋喃糖基-(1→4)-β-D-葡萄吡喃糖苷(E)和薯蓣皂苷元(F)。 在化合物的结构研究中,除使用红外、质谱,还综合运用了各种
【Abstract】 Paris Polyphylla Smith as a famous folk medicinal herb in China has been used not only as an anti-cancer, anti-biotic and anti-inflammatory drug but also to treat snake bite, parotitis, mastitis, chronic bronchitis, injuries from fractures as well as to stop bleeding.This thesis dealed with the extraction and systematic isolation of Paris Polyphylla Smith, as well as the structure elucidation of the compounds isolated from this plant. Modern techniques combined with traditional methods, especially the column chromatography over silica gel, D-101 highly porous polymer resin, Sephadex LH-20 and RP-18, were adoped in the experiment. Six pure compounds have been extracted and isolated. They were CH3(CH2)14COOH (A), C57H104O6 (B), 25R-diosgenyl-3-O-α-L-rhamnopyranosyl-(1→ 2)-[α-L-arabinofuranosyl-(1→ 4)]-β-D-glucopyranos ide(C), 25R-diosgenyl-3-O-α-L-rhamnopyranosyl-( 1→ 4)-α-L-rhamnopyr anosyl-(1→4)-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside(D),25 R-pennogenyl-3-O-α-L-rhamnopyranosyl-(1→ 2)-[a-L-arabinofuranosyl-(1→ 4)]-β-D-glucopyranoside (E) and diosgenin (F).
