[A rapid and nondestructive study of Yi herbs Dahongpao and Jigen with fourier transform infrared spectroscopy].
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-' 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.
