Objective: To determine the content of puerarin in the concentrating process of Xiaoke pills rapidly by near-infrared spectroscopy. Method: Near-infrared transmissionspectroscopy technology and fiber optic probe were used to collect NIR spectra of Xiaoke pills concentration liquid.With HPLC analysis results as reference
the fast determination method of puerarin was established with partial least squares (PLS). Result: The R2
RMSECV and RPD of the calibration model for puerarin were 0.955 9
0.241 and 4.36
respectively.The average relative deviation of the predication set was 1.8%. Conclusion: The method is accurate
fast and simple
which could be generalized to the on-line quality control of Xiaoke pills concentrating process.
