Currently,near infrared spectroscopy（ NIRS） has been considered as an efficient tool for achieving process analytical technology（ PAT） in the manufacture of traditional Chinese medicine（ TCM） products. In this article,the NIRS based process analytical system for the production of salvianolic acid for injection was introduced. The design of the process analytical system was described in detail,including the selection of monitored processes and testing mode,and potential risks that should be avoided. Moreover,the development of relative technologies was also presented,which contained the establishment of the monitoring methods for the elution of polyamide resin and macroporous resin chromatography processes,as well as the rapid analysis method for finished products. Based on author＇s experience of research and work,several issues in the application of NIRS to the process monitoring and control in TCM production were then raised,and some potential solutions were also discussed. The issues include building the technical team for process analytical system,the design of the process analytical system in the manufacture of TCM products,standardization of the NIRS-based analytical methods,and improving the management of process analytical system. Finally,the prospect for the application of NIRS in the TCM industry was put forward.
