Rapid Determination of Puerarin in Dry Pills of Xiaoke Pills by Near-infrared Spectroscopy
Objective:To determine the content of puerarin in dry pills of Xiaoke pills rapidly by near-infrared spectroscopy. Method: Near-infrared diffuse reflectance spectroscopy technology was used to collect NIR spectra of the dry pills. With HPLC analysis values as reference
the fast determination method for puerarin was established with partial least squares (PLS). Result: R2
RMSECV and RPD of the calibration model for puerarin were 0.948 2
0.248 and 4.40
respectively. The average relative deviation of the predication set was 3.51%. Conclusion: The method is accurate
fast and simple
which could be generalized to the quality monitor of intermediates and on-line quality control in the manufacture process of the Xiaoke pills.
