METHOD FOR CHEMICAL PATTERN RECOGNITION OF AUTHENTICITY OF TRADITIONAL CHINESE MEDICINE CHINESE HONEYLOCUST SPINE BASED ON NEAR-INFRARED SPECTROSCOPY

摘要

Provided is a method for chemical pattern recognition of the authenticity of the traditional Chinese medicine Chinese honeylocust spine based on near-infrared spectroscopy. The method uses the combination of a near-infrared spectroscopy acquisition method, a first-stage 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 traditional Chinese medicine Chinese honeylocust spine, such that the results of the pattern recognition method are accurate and reliable, and Chinese honeylocust spine 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 Chinese honeylocust spine based on near-infrared spectroscopy, can accurately distinguish between Chinese honeylocust spine and counterfeits thereof, and provides scientific basis for the quality evaluation of Chinese honeylocust spine.
