Abstract: The infrared spectrum has the advantages of high sensitivity,easy operation and strong specificity of bands.It is especially suitable for the rapid identification of Chinese herbal medicines.In this paper,ATR-MIR(attenuated total reflectance mid-infrared spectroscopy)was used to measure Baizi Yangxin pills and Niuhuang Jiedu pills,and then the two drugs were identified by chemometrics.The results show that the mid-infrared spectroscopy combined with chemometrics can achieve rapid detection and identification of Chinese herbal medicines.

Key words: infrared spectroscopy, Chinese herbal medicines, principal component analysis, derivative
