摘　　要：目的分析比较人参皂苷Rh2和20-(s)-Rh2的光谱结构。方法应用红外光谱和拉曼光谱对人参皂苷Rh2和20-(s)-Rh2的结构进行了比较研究。结果两者的红外光谱基本无差异。在拉曼光谱中,Rh2和20-(s)-Rh2的特征峰有些区别。结论 Rh2分子结构中20位羟基空间取向的不同,影响了Rh2和20-(s)-Rh2 C20-C30柔性链的堆积方式以及空间位置,说明在Rh2分子中有20-(R)-Rh2的存在。Objective To analysis and compare the spectral structure of ginsenoside Rh2 and 20-（ s）-Rh2. Methods Infrared and Raman spectrum have been applied in this article to compare the structures of ginsenoside Rh2 and 20-（s）-Rh2. Results There were no differences in the Infrared spectroscopy. However, some distinctions exist in both characteristic peaks. Conclusion The accumulation of flexible chain and its spatial position have been influenced by the difference of the hydmxy spatial orientation at C20, which illustrate that the existence of ginsenoside 20-（R）-Rh2.
