Abstract:
In this paper, near infrared spectroscopy (NIRS)-based total quality control system of compound Ejiao oral liquid is introduced briefly, including the quality control of raw traditional Chinese medicine (TCM) materials, monitoring and control of the extract and the alkaline precipitation technics, and also the inspection of finished products in both open bottle and non-opening modes. By analyzing and summing up the significance and difficulties, several important problems in the practical applications of NIRS technology are proposed, which will provide references for the similar studies of other TCM products.
