title: [A rapid method for identification of genus lycium by FTIR spectroscopy].
abstract: 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.
