摘要
建立了近红外光谱(NIR)法测定广金钱草药材中的浸出物含量。采用偏最小二乘法对109批广金钱草中浸出物的测定结果与NIR建立定量校正模型,并用21批验证集样品对模型进行验证及方法学考察。所建立的校正模型,内部交叉验证决定系数为0.979,校正均方差为0.311,预测均方差为0.331,内部交叉验证均方差为0.568。
A near-infrared spectroscpoy （NIR） method was established for the determination of extracts content in Desmodium styracifolium. The quantitative calibration models of NIR were established by the partial least squares method for the extract content and the NIR data of 109 batches olD. styracifolium samples, approved by 21 samples for model validation set validated and methodological study. The correlation coefficients, root-mean-square error of calibration, root- mean-square error of prediction and root-mean-square error of cross-validation of the calibration model were 0.979, 0.311, 0.331 and 0.568, respectively.
