利用近红外光谱(NIRS)和OPUS/Ident软件,通过计算采集到的样品的近红外光谱图之间的欧氏距离来反映不同鹿茸样品间的差异,对不同产地、不同种类的鹿茸进行了分类鉴别(Identification).结果表明,与传统方法繁琐复杂,主观性大相比,近红外光谱法能实现鹿茸的快速、无损和可靠的分析鉴别,为鹿茸的质量鉴别提供了一个客观有效的方法.

In the qualitative analysis of pilose antler by fourier transform-near infrared spectrometry (FT-NIRS) with the software OPUS/Ident,discrimination and identification of samples of different species and geographical origins was performed by collecting their NIR spectra and calculating the Euclidean distances,i.e the spectral distances D,among the spectra. It was proved by the analytical results that the FT-NIRS is a better and more reliable method,for its special features of rapidity and non-destructive,in comparing with the conventional methods,which are laborious and time-consuming. It was also shown that the results obtained by FT-NIRS were more objective than those obtained by the conventional methods,which depend much on the subjective judgement of experienced analytical chemists.
