目的 建立快速鑒別地榆及其炮制品地榆炭配方顆粒的紅外方法。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)光譜法分析地榆及其炮制品配方顆粒的光譜特征。結(jié)果 地榆與炮制品配方顆粒的紅外光譜基本相似，僅在2 932、1 041、918、760 cm^-1處位置變化；二階導(dǎo)數(shù)光譜在1 200～1 800 cm^-1差異較大，二維相關(guān)光譜圖差異明顯。結(jié)論 通過(guò)比較地榆及其炮制品紅外光譜圖、二階導(dǎo)數(shù)光譜圖及二維相關(guān)光譜圖，可以準(zhǔn)確、快速鑒別地榆及其炮制品地榆炭配方顆粒。

Objective To establish a rapid FTIR method for identifying of different processed products of Sanguisorbae Radix Formula Granules. Methods Different processed products of Sanguisorbae Radix Formula Granules were researched by infrared、second derivative spectra and two-dimensional correlation spectroscopy.Results The infrared spectra of two formula granules were similar, while the position of the peaks were different in 2 932, 1 041, 918, 760 cm^-1. In second derivative spectra, the intensity, shape and position of the peaks were different in the range of 1 200-1 800 cm^-1, Two-dimensional correlation spectroscopy were obvious difference. Conclusion By comparing the infrared spectra, second derivative spectra and two-dimensional correlation spectroscopy of different processed products. It can be identified rapidly and accurately of different processed products of Sanguisorbae Radix Formula Granules.
