Fifteen samples of original plants of Rhizoma Cimicifuga were determined quickly and directly with the method of FTIR and comparing software. The results showed that the spectra of these samples were characteristic relying on the difference of chemical components and their content of related components. The difference of spectra among samples belonging to different families was distinct, and in different species with same genus too. To the same species, between two samples with different producing areas, or with same producing area but different collection date, the spectra were not obvious. This approach provide a quickly and accurately determination method of crude drug without extraction and separation.
采用傅里叶变换红外光谱（FTIR）法及比对软件，对15份升麻原植物样品进行了快速直接测定。结果表明，这些样品的光谱具有特征性，这取决于化学成分的差异及其相关成分的含量。不同科的样品间光谱差异明显，同属不同种的样品间光谱差异也明显。对于同一种植物，不同产地的两个样品间，或同一产地但不同采收日期的样品间，光谱差异不明显。该方法提供了一种无需提取分离即可快速准确地测定生药的方法。
