ABSTRACT
Objective To determine the moisture content in Polygoni multiflori Radix rapidly by near-infrared spectroscopy. Methods The moisture content of the samples were determined by oven drying method and the near-infrared spectrum data were collected by near-infrared spectroscopy.The quantitative test model of moisture content in Polygoni multiflori Radix was established by chemometrics methods and was validated with validation samples. Results The correlation coefficients, root-mean-square error of calibration (RMSEC), root-mean-square error of predication (RMSCP) and the root-mean-square error of cross-validation ( RMSECV ) of the calibration model was 0. 984 75, 0. 161, 0. 181 and 0. 471 64, respectively.The absolute deviation of the analytical and predictive values of 21 validation samples was -0.35%-0.28%, and the average recovery was 99. 87%. Conclusion Near-infrared spectroscopy can be used to determine the moisture content of Polygoni multiflori Radix rapidly and accurately.
