| 摘 要： | 采用近红外光谱测定人参与西洋参的主要皂甙总量.采集人参与西洋参的漫反射光谱,分别对光谱进行正交信号校正(OSC)与常规预处理,建立了对应的偏最小二乘(PLS)回归模型.与常规最优预处理方法相比,OSC能很好地消除人参与西洋参的品种差异,显著提高了光谱与皂甙含量的相关系数,同时降低了PLS建模因子数,提高了模型的稳健性与...

| Abstract: | Potential of NIR spectroscopy to determine total main ginsenosides contents in Chinese ginseng and American ginseng was studied.Diffuse reflective spectra of all samples were collected.Then the raw spectra were preprocessed with orthogonal signal correction(OSC) and routine methods respectively.After that,the corresponding partial least-squares(PLS) regression models were developed.Comparing with the optimal routine spectral preprocessing method,OSC can eliminate the sample species differences perfectly and... |
