摘要
目的 :探讨常用中药的组合——“对药”和非“对药”间 ,在化学成分、分子结构、构型、构象方面的相似性差异。方法 :(1 )按中药多分子体系的脂溶性差异 ,分为石油醚、氯仿、乙酸乙脂、乙醇和水的溶出性成分集合 ,然后进行“对药”与非“对药”的对比分析 ;(2 )用紫外 -可见光光度计测定吸收光谱曲线。结果 :分析2 2 5份样品 ,约 1 30 0个数据 ,9对“对药”中有 6对分别显示 :紫外 -可见光吸收光谱峰的分布区域重叠较大 ;相同波峰数和相同波谷数较多 ;组合后吸收光谱曲线下面积增加趋势较大。结论 :提示化学成分相近 ,分子结构或构型、构象相似是中药 (植物药 )组方配伍的原则之一。
Objective:To study the difference between the pairing herbs i.e. commonly used combinations of two Chinese medicinal herbs,and nonpairing herbs in the similarity of chemical components and their molecular structure (configuration and conformation).Methhods:1:The chemical components of Chinese herbal medicines(singles or combinations) extracted with petroleum ether,chloroform, ethyl acetate,ethenol and water respectively were analyzed and compared.2.The specimens were analyzed with ultraviolet visible absorption spectrophotometry.Results:1300 data were obtained from 225 specimens analysed.6 out of 9 pairs of compactible herbs showed wider range of overlaped ultraviolet visible absorption peaks and relatively more identical peaks and trough and the areas under the curves showed a tendency to increase.Conclusion:The similarity of chemical components,and their molecular structure (configuration and conformation) was one of the mechanisms of the compactibility and combinability of Chinese medicinal herbs.
