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.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
