Objective To establish a rapid FT-IR method for identifying 3 Formula Granules of Curcumae Radix, Curcuame Rhizoma and Curcumae Longae Rhizoma. Methods FT-IR corresponding second derivative spectra and two-dimensional correlation spectroscopy were applied to analyze the spectral characteristic of Curcumae Radix, Curcuame Rhizoma and Curcumae Longae Rhizoma Formula Granules. Results The second derivative spectra of different Formula Granules were significantly different in the range of 800-1 800 cm-1, and the two-dimensional correlation spectra were significantly different. Conclusions By comparing the infrared spectra, second derivative spectra and two-dimensional correlation spectroscopy of different products. It can be identified rapidly and accurately of Curcumae Radix, Curcuame Rhizoma and Curcumae Longae Rhizoma Formula Granules.
