Chinese journal of experimental traditional medical formulae, 2013, 19(8): 146-149. DOI: 10.11653/syfj2013080146.
Objective: To determine the content of Magnolol in Huoxiang Zhengqi capsules by near-infrared spectroscopy(NIR). Method: Determined the content of magnolol in 109 samples by HPLC. Collected their NIR spectrograms data
calibration model of magnolol was established by the Partial least squares regression analysis. Result: The correlation coefficients (R2)
the root-mean-square error of cross-validation and the root-mean-square error of calibration (RMSEC) of the calibration model for magnolol were 0.945 6
0.054 3
0.024 5; and the root-mean-square error of prediction (RMSEP) was 0.045 9
the average rate of recovery was 101.26%. Conclusion: The method is steady
accurate
and can be applied for the fast determination of magnolol within. Huoxiang Zhengqi capsules.
