Rapid Determination of Water-extract in Jingutongxiao Pills by Near-infrared Spectroscopy
Objective: To rapid determine the content of water-extract in Jingutongxiao pills by near-infrared spectroscopy (NIRS) combined with partial least squares (PLS). Method: The near-infrared spectra was associated with the content of water-extract in Jingutongxiao pills
and the spectral pretreatment method and modeling interval were studied. The quantitative analysis model of water-extract in Jingutongxiao pills was established by combining the NIRS with PLS. Result: The 98 samples of the quantitative analysis model for correlation coefficients (R2)
root mean square error of calibration (RMSEC) and root mean square error of predication (RMSEP) were 0.983 26
0.21 and 0.22
respectively. 18 validation samples of real value and prediction value of the mean relative deviation is 0.09%. Conclusion: It is feasible to rapid determine the content of water-extract in Jingutongxiao pills by NIRS and PLS.
