ABSTRACT
The identification of Chinese materia medica (CMM) characters, an important part of the quality standard of CMM, is one of the overall quality indicators of CMM. It is an old technical problem facing the inheritance and innovation of experience identification of Chinese medicine industry. However, the regulation of CMM characters recorded in the Chinese Pharmacopoeia and other local drug standards and processing specifications are still staying at words description, relying on human sensory judgment, so the operability needs to be improved. This paper puts forward the proposal to establish a quality standard for CMM identification for the use of reference herbal pieces and Chinese medicinal herb for the identification of characters, and provides basic support for the objective digital research of CMM characters identification, which is helpful to improve the quality evaluation of CMM.
ABSTRACT
In recent years, near-infrared spectroscopy has developed into an analytical technique widely used in various fields. Because of its advantages of fast, green and non-destructive, it plays an increasingly prominent role in the field of traditional Chinese medicine (TCM) analysis. However, due to the complexity and overlap of spectra, near-infrared spectroscopy needs to be combined with chemometrics for analysis and calculation. The principle, application scope, advantages and limitations of near infrared spectroscopy and chemometrics are summarized in detail, in addition, their combined applications in the identification of the origin, authenticity, processed products, composition prediction and water content detection of TCM are reviewed. The authors discussed and analyzed the joint application of near-infrared spectroscopy and chemometrics in the field of TCM analysis, and summarized the unique advantages of the combined technology in the field of TCM, which had certain guiding significance for medical workers to better use this technology.
