title: [A rapid method for the identification of four different features of gouqizi by FTIR spectrometry].
abstract: 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.
