目的 建立人參、紅參、西洋參3種配方顆粒的傅里葉變換紅外光譜快速鑒別方法。方法 采用紅外光譜及其二階導數(shù)光譜、二維相關光譜，分析不同配方顆粒的紅外光譜特征。結果 傅里葉變換紅外光譜能夠從整體上反映化學成分的不同情況，二階導數(shù)光譜和二維相關光譜在800~1800 cm^-1能夠?qū)Σ煌浞筋w粒進行不同程度的區(qū)分，二維相關光譜的區(qū)分效果明顯。結論 通過綜合比較傅里葉變換紅外光譜、二階導數(shù)光譜和二維相關光譜，可以準確、快速鑒別人參、紅參、西洋參3種配方顆粒。

Objective To establish a rapid FT-IR method for identifying 3 Formula Granules of Ginseng, Red Ginseng and American Ginseng.Methods FT-IR alongwith corresponding second derivative spectra and two-dimensional correlation spectra were applied to analyze different Formula Granules of Ginseng, Red Ginseng and American Ginseng.Results FT-IR holistically demonstrated the different chemical features. In the range of 800~1800 cm^-1, the second-derivative spectra and two-dimensional correlation spectra effectively distinguished different Formula Granules, between which the latter was superior. Conclusion By comprehensively comparing the FT-IR and corresponding second derivative spectra and two-dimensional correlation spectra, identification for 3 Formula Granules of Ginseng, Red Ginseng and American Ginseng could be realized rapidly and accurately.
