The invention belongs to the technical field of Chinese medicinal material detection, and provides a method of detecting Chinese medicinal materials by infrared spectroscopy. The method specifically uses infrared spectroscopy to detect adulterated angelica slices and adulterated codonopsis slices and identify astragalus mongholicus slices. An infrared spectrometer is used, infrared spectrum relevant characteristic peaks and a simple algorithm are combined for data analysis, clear and direct identification can be carried out when 5% of European angelica is adulterated in an angelica sample; quantitative verification is carried out through high performance liquid chromatography; the whole identification process does not destroy the sample, the identification is quick, accurate and stable, and the method can also be applied to detection of Saposhnikovia divaricata adulterated in the codonopsis slice and identification of authenticity of astragalus mongholicus. 本发明属于中药材检测技术领域，提供了一种红外光谱检测中药材的方法。该方法具体是利用红外光谱检测掺假当归饮
