摘要: 本文主要研究近红外光谱法在快速测定木香药材中木香烃内酯与去氢木香内酯含量的应用。采用近红外漫反射光谱法采集木香的近红外光谱,以HPLC测量值为参考值,运用偏最小二乘法(PLS)建立木香烃内酯与去氢木香内酯含量的定量模型,并用未知样品验证该模型。结果表明所建定量模型的校正集内部交叉验证相关系数(R2)、校正均方差(RMSEC)和内部交叉验证均方差(RMSECV)分别为0.9783、0.161和0.374;经外部验证的预测相关系数(r2)和预测均方差(RMSEP)分别为0.9546和0.162。该方法操作简便,测定快速,结果准确,无污染,可用于木香药材中木香烃内酯与去氢木香内酯含量的快速测定。

Abstract: This paper mainly studied the application of near infrared spectroscopy for rapid determination of costunolide and dehydrocostus lactone in Radix Aucklandiae.Through collecting nearinfrared spectra of Radix Aucklandiae by Nicolet 6700 NIRS spectrometry,the quantitative model of costunolide and dehydrocostus lactone was created by partial least square (PLS) analysis using the quantification value obtained by HPLC as reference.The developed quantitative model was verified by the unknown samples.The results showed that the correlation coefficient (R2), the root-mean-square error of calibration (RMSEC) and the root-mean-square error of cross-validation (RMSECV) of the quantitative model of costunolide and dehydrocostus lactone was 0.9783,0.161 and 0.374,respectively;the correlation coefficients of prediction (r2) and the root-mean-square error of prediction (RMSEP) was 0.9546 and 0.162,respectively.The developed method was simple,quick,accurate,and it can be applied for the rapid determination of costunolide and dehydrocostus lactone in Radix Aucklandiae.
