目的 建立快速鑒別郁金、莪術(shù)、姜黃配方顆粒的紅外光譜方法。方法 采用紅外光譜結(jié)合二階導(dǎo)數(shù)光譜及二維相關(guān)光譜法分析郁金、莪術(shù)和姜黃配方顆粒光譜特征。結(jié)果 不同配方顆粒二階導(dǎo)數(shù)光譜在800～1 800 cm^-1范圍內(nèi)差異較大，二維相關(guān)光譜圖差異明顯。結(jié)論 通過比較紅外光譜圖、二階導(dǎo)數(shù)光譜圖及二維相關(guān)光譜圖，可以準(zhǔn)確、快速鑒別郁金、莪術(shù)、姜黃配方顆粒。

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.
