Abstract：Two Yi herbs were studied by ATR Fourier transform infrared spectroscopy in the present paper. The main characteristic peaks of Jigen are: 1 726 and 1 641 cm-1 (broad peak), 1 505 cm-1(small peak), four finger small peaks near 1 379 cm-1, 1 244 cm-1(small sharp peak), 1 512 cm-1(small peak), 1 438 cm-1(small sharp peak), and 1 044 cm-1(strong, single peak). The results show that Jigen and Dahongpao have different characteristic infrared spectra. FTIR has proved to be a rapid, simple and nondestructive method to discriminate Yi herbs. Besides, test indicates that the two Yi herbs have a characteristic in common: absorbance at 1 034 cm-1 is the strongest, which is attributed to stretching of C—O—C, indicating that the spectra of the Yi herbs root is mainly composed of the adsorption of carbohydrates, lignin, cellulose etc.
