FTIR直接鉴别植物生药材

Direct Determination of Raw Plant Drugs by FTIR

本文首次利用傅里叶变换红外光谱法的漫反射采样技术，快速、直接地测定了２５种常用植物生药材。结果表明：各种中药材由于其化学成分的不同使得每种药材都有自己独特的红外谱，据红外特征吸收均能达到分类鉴别、种类认定的目的。该方法具有快速、准确、制样简单不需对样品进行提取分离等特点。

Twenty five common raw plant drugs were determined quickly and directly with diffuse reflectance drawing sample of FTIR for the first time.The results show that the drugs with different chemical compounds are characteristics of different peaks.The category of plant drugs may be firmly identified through their respective IR characteristic absorption spectrum.Furthermore,the approach can be achieved quickly and accurately without extraction and separation of samples.
