摘要

摘要: 目的采用近红外光谱（NIR）透射法快速测定栀子逆流提取过程中栀子苷含量。方法以HPLC测定值作为参照，采用近红外光谱（NIR）透射法，结合偏最小二乘法（PLS）建立栀子苷含量的快速测定方法。结果建立的栀子逆流提取液中栀子苷校正模型的相关系数（R）、校正均方差（RMSEC）分别为0.997，0.113。经外部验证，校正模型的预测均方差(RMSEP)为0.132，预测值和真实值相关系数达到0.996。结论 NIR可以作为一种准确、快速、无损的检测方法用于中药逆流提取过程有效成分含量的变化规律。

Abstract: OBJECTIVE To rapidly determine geniposide content during gardenia countercurrent extract process through near infrared spectroscopy(NIR). METHODS NIR combined with partial least squares (PLS) was established to rapidly determine geniposide content with HPLC as the reference. RESULTS The geniposide correlation coefficient (R) and root-mean-square error of calibration (RMSEC) were respectively 0.997 and 0.113. After an external validation， the root-mean-square error of prodiction (RMSEP) was 0.132 and the correlation coefficient of predicted and true values reached 0.996. CONCLUSION NIR can be used as a kind of accurate， rapid and nondestructive detection method applied in studing changes of active ingredients content during traditional Chinese medicine countercurrent extraction process.
