Application Of Near Infrared Spectroscopy Conformity Test, Correlation Coefficient And PLS To Identification And Quantitative Analysis Of Traditional Chinese Medicine

Drug counterfeiters are becoming more sophisticated with the use of a variety of inspection techniques can be verified from multiple levels of genuine and fake drugs. Among them, the near-infrared spectroscopy is a fast and simple technology, not only for the qualitative and quantitative detection of drug products, but also through the rapid analysis of Chinese herbal extracts to determine the merits of true and false.In this paper, near infrared spectroscopy in the quality of Chinese medicine in the identification and application of quantitative analysis of preliminary exploration. Main tasks are:1. For fraud exists in the phenomenon of modern Chinese medicine products, this proprietary near infrared spectroscopy technology to identify the authenticity of thirty-seven study, by getting thirty-seven the near infrared spectrum, the use of identification to establish consistency model identification method model, the authenticity of thirty-seven for fast, accurate identification.2. For the recent production of proprietary Chinese medicines, and some manufacturers to cut costs, without changing the production process, adding not be extracted into the extract, but tied directly to the medicinal powder mixed case of granulation, the use of near infrared spectrum correlation coefficient method test model compound Danshen tablets, used in the rapid screening of market supervision, to effectively determine the authenticity of Danshen products.3. Using near infrared diffuse reflectance spectroscopy, the use of partial least squares method to establish calibration model, cornus officinalis in Loganin content of ursolic acid and determination, the results show that the method is rapid, accurate, non-destructive, can be applied purchased in large quantities and production companies before the raw materials of the merits of identification.Through the above studies have shown that near infrared spectroscopy in rapid identification of traditional Chinese medicine has a broad prospect.
