Application Status of Near Infrared Spectroscopy Combined with Chemometrics in Analysis of Traditional Chinese Medicine / 中国实验方剂学杂志

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.
