In this article, a method of using Fourier-transform infrared (FTIR) spectrometry to identify four Lyeium barbarum L. (Gouqizi) in turn of colour, shape, taste and water content. The four features (include color is red or black, shape is round or long, quality is dry or wet, taste is sweet or bitter) are related with the FTIR absorption peaks, this is based on the chemical components and their relative contents are different in various Gouqizi. These differences can be reflected in the FTIR spectra. So a new idea is brought up in the research area of identification of traditional Chinese medicine. Alao, FTIR is proved to be a rapid, simple, reliable and non-destructive qualification method.
本文介绍了一种利用傅里叶变换红外（FTIR）光谱法依次从颜色、形状、味道和含水量方面鉴别四种枸杞的方法。这四个特征（包括颜色为红色或黑色、形状为圆形或长形、质地为干或湿、味道为甜或苦）与FTIR吸收峰相关，这是基于不同枸杞中的化学成分及其相对含量不同。这些差异可以在FTIR光谱中得到体现。因此，为中药鉴别研究领域提出了一个新思路。此外，FTIR被证明是一种快速、简单、可靠且无损的鉴定方法。
