淫羊藿和柔毛淫羊藿作为常用中药,其活性成分朝藿定A、朝藿定B、朝藿定C和淫羊藿苷对药理作用具有重要影响。该研究采集了淫羊藿与柔毛淫羊藿的台式与便携式近红外光谱数据,并结合HPLC测定其中的朝藿定A、朝藿定B、朝藿定C和淫羊藿苷含量,进而建立了偏最小二乘回归(PLSR) 模型与支持向量回归(SVR)模型。为实现台式近红外光谱数据与便携式近红外光谱数据之间的模型适配与转移,该研究探索了两种标样集选择方法:层次聚类法与SPXY算法,并应用两种模型转移方法:直接标准化法(DS)和分段直接标准法(PDS)。研究结果表明,标样集选择方法与模型转移方法对模型转移效果具有显著影响。通过配对
t
检验进一步验证,最佳转移模型的预测值与真实值之间无显著差异(
P
值均大于0.05),表明所建立的转移模型在不同仪器间具有较好的适应性。该研究为近红外光谱技术在淫羊藿与柔毛淫羊藿的定量分析与模型转移方面的研究提供了依据。
Epimedium brevicornum
and
Epimedium pubescens
are commonly used traditional Chinese medicines,and their active ingredients such as epimedin A,epimedin B,epimedin C and icariin have important effects on pharmacological effects. In this study,the desktop and portable near-infrared spectral data of
Epimedium brevicornum
and
Epimedium pubescens
were collected,and the content data of Epimedin A,Epimedin B,Epimedin C and Icariin were determined by HPLC,and then the partial least squares regression(PLSR) model and support vector regression(SVR) model were established. In order to realize the model adaptation and transfer between desktop near-infrared spectral data and portable near-infrared spectral data,two standard sample set selection methods were explored in the study:hierarchical clustering method and SPXY algorithm,and two model transfer methods were applied:direct correction(DS) method and piecewise direct correction(PDS) method. The results show that the standard sample set selection method and the model transfer method have significant impacts on the model transfer effect. Further verification by paired
t
test showed that there was no significant difference between the predicted value and the real value of the optimal transfer model (
P
>
0.05),which indicated that the established tra
nsfer model had good adaptability among different instruments. This study provides a basis for the quantitative analysis and model transfer of
Epimedium brevicornum
and
Epimedium pubescens
by near infrared spectroscopy.
