Application of near infrared spectroscopy to the analysis and fast quality assessment of traditional Chinese medicinal products

Near infrared spectroscopy (NIRS) has been widely applied in both qualitative and quantitative analysis. There is growing interest in its application to traditional Chinese medicine (TCM) and a review of recent developments in the field is timely. To present an overview of recent applications of NIRS to the identification, classification and analysis of TCM products, studies describing the application of NIRS to TCM products are classified into those involving qualitative and quantitative analysis. In addition, the application of NIRS to the detection of illegal additives and the rapid assessment of quality of TCMs by fast inspection are also described. This review covers over 100 studies emphasizing the application of NIRS in different fields. Furthermore, basic analytical principles and specific examples are used to illustrate the feasibility and effectiveness of NIRS in pattern identification. NIRS provides an effective and powerful tool for the qualitative and quantitative analysis of TCM products.

Chemical identification technology, rapid TLC technology, NIRS technology and microscopy technology are basic parts in fast inspection platform. Advantages of NIRS are respected to solve problems of less sample size, longer test periods and higher cost for quality control of TCM productions.Figure optionsDownload as PowerPoint slide
