摘　　要：本文利用傅里叶变换红外光谱法和计算机比对软件 ,快速、直接地测定了 15种升麻基源植物 ,结果表明 :各种升麻药材的基源植物由于其化学成分的不同以及各成分间的相对含量的不同 ,使每种样品都有自己独特的红外谱图。不同科的升麻样品谱图差别较显著 ;同属不同种的升麻谱图差别较大 ;同种不同产地、同种同产地不同采集时间的升麻谱图差别较小。该方法具有快速、准确、制样简单不需对样品进行提取分离。Fifteen samples of original plants of Rhizorna 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 I and in different species with same genus too. To the same species, between two samples with different producting areas, or with same producting 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.
