Rapid Determination of Moisture Content in Polygoni Multiflori Radix Praeparata by Near Infrared Spectroscopy
Objective: To establish a method for determination of the moisture in Polygoni Multiflori Radix Praeparata by near-infrared spectroscopy (NIRS). Method: The moisture content of 135 samples was determined by the method of drying under oven. The second derivative and the standard normal variate (SNV) were used as spectral preprocessing options
and calibration model of moisture content was established by the partial least squares regression analysis. Result: The correlation coefficients
the root-mean-square error of calibration
the root-mean-square error of predication and the root-mean-square error of cross-validation of the calibration model for moisture content were 0.990 71
0.152
0.175 and 0.482 57. Conclusion: The method is convenient
accurate
reliable and it is of high reproducibility and can predict moisture content of Polygoni Multiflori Radix Praeparata rapidly.
