| Abstract: | Use of PLS and near-infrared spectroscopy for non-destructive quantitative analysis of Belladonna Powder, and the best mathematic calibration model were built simultaneously. Furthermore the three pretreated spectra were used and compare, and the numbers of principal component＇s affection on the prediction ability of PLS were discussed. The prediction set was predicted, and the results were satisfied. |
| Keywords: | Short-wavelength near-infrared spectroscopy Partial least squares（PLS） non-destructive quantitative analysis Belladonna Powder |
