Objective: To determine the content of Aconitum monoester alkaloids (AMA) in Guifu Zhitong cataplasm (GZC) by near infrared spectroscopy (NIR). Method: NIRs of 53 batches of GZC samples were determined by using TQ Analyst 8.0 software. Within the wavebands between 10 000-4 000 cm-1
one main factor was selected from the primary spectrum. The quantitative calibration determination model was established with partial least squares (PLS). Result: The established quantitative calibration model showed a good correlation coefficient (r=0.942 0)
low root mean square error of calibration (RMSEC) at 0.013 5
root mean square error of prediction (RMSECV) of 0.014 4
with the average predicted recovery rate of validation set of 101.44%. Conclusion: The quantitative calibration model can predict the content of alkaloids in GZC accurately and so can be used for the quality control of aconitum monoester alkaloids in GZC.
