| 摘 要： | 本文用偏最小二乘（PLS）算法解析中草药秦皮中有效成分秦皮甲素、秦皮乙素的近红外（NIR）透射光谱,避免了繁杂的分离处理过程。预测了14种秦皮中的秦皮甲素、秦皮乙素浓度。讨论了波长范围、主成分数以及导数光谱对预测结果的影响。用HPLC法测定值作标准,秦皮甲素预测值的相对误差RE（%）〈5.32%;当秦皮乙素浓度〉0.30%时,预测值的RE（%）〈25%。初步证明PLS算法-NIR透射光谱可以用于中草药中的多组分测定。 |

| Abstract: | In this paper,partial least squares(PLS)algorithm was used to parse near infrared(NIR)transmission spectra of the aesculin and aesculetin in cortex fraxinis without fussy separating.The contents of aesculin and aesculetin,which was extracted from 14 cortex fraxinis,has been predicted.The effect of the best wavelength range,the numbers of principal components and derivative NIR on the results was discussed.Compared the results with those of HPLC,the relative errors(RE%)of aesculin was less than 5.32%,and les... |
