摘要

目的：运用近红外光谱（NIR）技术检测甘草药材中的甘草苷、甘草酸及水分。方法：采用积分球漫反射扫描近红外光谱，以TQ Analyst软件进行数据分析，建立甘草中甘草苷、甘草酸及水分测定的NIR。结果：甘草苷的预测均方根误差（RMSEP）为0.165，预测集相关系数（Rp）0.986 8；交叉验证均方根误差（RMSECV）为0.393

校正集相关系数（Rv）0.904 6。甘草酸的RMSEP=0.166， Rp=0.995 5；RMSECV=0.575

Rv=0.954 0。水分的RMSEP=0.137，Rp=0.995 2；RMSECV=0.498， Rv=0.931 9。结论：该方法快速、简便。可以用于甘草中甘草苷、甘草酸及水分的含量测定。

Abstract

Objective: To determine the contents of liquiritin

licorice acid and moisture in Glycyrrhizae Radix et Rhizoma by using near-infrared (NIR) quantification method. Method: Near-infrared diffused reflected spectroscopy was applied to obtain the NIR spectra of Glycyrrhizae Radix et Rhizoma and the content values were analyzed by using TQ Analyst software. The NIR method was established with partial least squares (PLS). Result: The root-mean-square error of prediction (RMSEP) value of licorice glycosides was 0.165

with correlation coefficient Rp value 0.986 8; root-mean-squares error of cross-validation (RMSECV) value was 0.393

with correlation coefficient Rv value 0.904 6.The RMSEP value of glycyrrhizic acid was 0.166

with correlation coefficient Rp value 0.995 5; the RMSECV value was 0.575

with correlation coefficient Rv value 0.954 0.The RMSEP value of moisture was 0.137

with correlation coefficient Rp value 0.995 2; RMSECV value was 0.498

with correlation coefficient Rv 0.931 9. Conclusion: The established method is accurate

rapid and convenient

which could be used for the content determination of liquiritin

licorice acid and moisture in Glycyrrhizae Radix.
