Abstract
Provided is a near-infrared spectroscopy-based method for chemical pattern recognition of the authenticity of the traditional Chinese medicine Gleditsiae Spina. The method uses the combination of a near-infrared spectroscopy acquisition method, a 1st derivative pretreatment method and a successive projection algorithm, a Kennard-Stone algorithm and a marching algorithm to perform chemical pattern recognition on the authenticity of the Gleditsiae Spina. The results of the pattern recognition method are accurate and reliable, and Gleditsiae Spina and counterfeits thereof can be accurately distinguished. The present application is the first to establish a method for the chemical pattern recognition of the quality of Gleditsiae Spina based on near-infrared spectroscopy, and can accurately distinguish between Gleditsiae Spina and counterfeits thereof, and provides scientific basis for the quality evaluation of Gleditsiae Spina.
