摘要
用傅里叶变换红外光谱法 (FTIR)无损快速鉴别了国产 10种枸杞。结果表明 :按其形态学分类的7种枸杞和 3变种枸杞与红外指纹图谱有一定的相关性 ,也有一些差异。这 10种枸杞的红外光谱各自均有自己的特征吸收 ,可方便地给以鉴别和区分 ,同时还进一步表明了枸杞中的化学组分之间的差异 ,为枸杞品种优良的宏观质控提供了一个快速、直观、方便。
In this article, a method of using Fourier-transform infrared spectroscopy (FTIR) to identify 7 species and 3 variations of genus lycium (Gouqi) in China is described. This method is based on the additive IR absorptions of the chemical components and the differences of their relative contents in various Gouqi. These differences are reflected in the FTIR spectra. The method provides a novel fingerprinting technique for the identification and differentiation of traditional Chinese medicine. Such technique can serve as a rapid, simple, reliable and non-destructive analytical method for Gouqi as a Chinese material medication.
