[Rapid identification and evaluation of Chinese materia medica quality by near infrared spectroscopy].

In recent years, the research object of traditional Chinese medicine(TCM) analysis has not just been limited to the common analysis technology, but focused on the key relationship between chemical ingredients and traditional functions, including Chinese material medica (CMM) attributes, chemical substance and biological function. Near infrared spectroscopy (NIR) analysis technology, due to its unique advantages, has been developed rapidly in the field of pharmaceutical analysis, especially in the TCM analysis. NIRS can reflect the global chemical information comprehensively, and this holistic approach can be used for the identification and cluster analysis of CMM. On the other hand, inspiring by the concept of TCM quality markers (Q-markers), by means of the activity screening assay of the key components from the CMM, multiple bioactive components quantitation can be achieved by the NIRS combined with chemometrics. Taking the full advantage of the NIR technology, a simple and reliable method for the fast evaluation of the quality of TCMs can be provided. Therefore, the progress and trend of modern TCM quality evaluation by NIR are discussed and prospected in the present review.
