| Abstract: | Objective:To develop near-infrared spectroscopy (NIR) quantitative analysis model for water-soluble extract in Prunellae Spica. Method:The extract content of Prunellae Spica in 180 batches was determined by hot dipping method. NIRS spectrograms were measured, and the quantitative analysis model for extract was established by TQ8.0 software. Result:The correlation cross-validation coefficients (R2), root-mean-square error of calibration (RMSEC) and root-mean-square error of prediction (RMSEP) of the quantitative calibration model for water extract were 0.9814, 0.347 and 0.378 respectively, and the test value of NIR prediction values and the reference values of the validation set was 0.653, bilateral P=0.517>0.05, implying the difference was not significant. Conclusion:The method is steady, accurate and reliable to predict the water extracts content of Prunellae Spica by NIR. |
