It is the objective of this study to establish quantitative models to detect quality indicators rapidly during theextraction process of Schisandrachinensis using using near-infrared (NIR) spectroscopy. NIR spectrum was collected on-line and PLSR models were developed for the contents of schisandrin , fructose, glucose and soluble solids, which were measured with HPLC and weight loss methods. For the cross validation of contents of schisandrin, fructose, glucose and soluble solids, the correlation coefficients were 0.99792, 0.99246, 0.99371 and 0.98723; RMSEC were 1.41, 0.0919, 0.0954 and 3.07; RMSEP were 8.76, 0.333, 0.448 and 11.2, respectively. In conclusion, NIR models were developed successfully to determine the quality indicators including the contents of schisandrin, fructose, glucose and soluble solids rapidly and accurately.
