摘要
应用近红外漫反射光谱法(NIRDRS)快速测定山茱萸中的马钱苷。扫描各样品的近红外光谱,运用偏最小二乘法建立含量与近红外光谱之间的模型,测定未知样品含量。所建立的马钱苷定量模型的内部交叉验证决定系数(R2)为0.958 95,校正均方根偏差(RMSEC)、交互验证均方根偏差(RMSECV)和预测均方根偏差(RMSEP)分别为0.034 4、0.062 5和0.094 8。
A near infrared diffuse reflection spectroscopy method was established for the rapid determination of loganin in Fructus corni. The NIR spectra of the powdered Fructus corni were collected, and the partial least squares （PLS） was developed to correlate the spectra and the corresponding HPLC values. The correlation coefficient （R2） of the calibration model for loganin was 0.958 95, while root mean square error of calibration （RMSEC）, root mean square error of cross validation （RMSECV） and root mean square error of predication （RMSEP） were 0.034 4, 0.062 5 and 0.094 8, respectively.
