中草药绞股蓝的傅里叶变换红外和拉曼光谱分析

The Analysis of Gynostemma Pentaphyllum(Thunb) Makino for Chinese Crude Drug by FTIR and FT-Raman

利用傅里叶变换红外和拉曼光谱法直接、快速地测定了中草药绞股蓝样品 ,并对所测样品的红外、拉曼光谱图进行比较。结果表明 ,红外光谱图中各吸收峰位置与拉曼光谱图中各散射特征峰位置相对应 ,其关系互补。采用傅里叶变换红外和拉曼光谱分析法 ,对中草药绞股蓝的成份研究和特征波谱的鉴别 。

The Gynostemma Pentaphyllum is an important plant for Chinese crude drug. To qualitatively analyse the Gynostemma Pentaphyllum(Thunb) Makino, FTIR and FT-Raman were used to identify the contents of it. The results show, that the trough of each absorption in the picture of FTIR spectrum and the characteristic wave crest of each dispersion in the picture of FT-Raman spectrum had parallelism at their position, their relation pairs with each other. This is useful for the further on-line quantitative analysis and quality control of the Gynostemma Pentaphyllum(Thunb) Makino. This approach provide a quickly and accurately determination method of crude drug with out extraction and separation.
