Objective: To develop a rapid NIR method for determination of paeoniflorin in paeony root. Method: HPLC was used as a reference method to determine the content of paeoniflorin. Multivariate calibration model based on PLS algorithm was developed to correlate the spectra and the corresponding values determined by the reference method. Result: the RMSECV of the model for paeoniflorin was 0.019 7
the correlation coefficients of the calibration models was 0.969 7
the RMSEP was 0.046 1. Conclusion: The NIR method was rapid
simple
and noninvasive and that is applied to determine the content of paeoniflorin in paeony root. It can offer reference to content determination of other Chinese herbs.
