HS-GC-IMS结合化学计量学快速鉴别不同产地枳壳

Identification of Aurantii Fructus from Different Origins by HS-GC-IMS with Chemometrics Methods

摘要

摘要:
目的建立快速分析枳壳挥发性成分的方法，比较不同产地枳壳挥发性成分的差异。
方法采用顶空气相离子迁移谱技术(HS-GC-IMS)分析不同产地枳壳的挥发性成分，运用聚类分析、主成分分析法和偏最小二乘法-判别分析进行不同产地枳壳分类。
结果共检测出80种挥发性化合物，鉴别其中55种，包含萜烯类13种、醛类18种、酯类5种、酮类8种、醇类8种、酸类2种、吡嗪类1种；通过聚类分析和主成分分析法可将不同产地枳壳进行区分。
结论该方法简便、经济、高效、直观，可用于识别和评价不同产地枳壳挥发性有机物的种类和差异，为枳壳产地鉴别和质量控制提供参考。

Abstract:
OBJECTIVE To establish a rapid analysis method of volatile components in Aurantii Fructus, and compare the differences of volatile components in Aurantii Fructus from different habitats.
METHODS The volatile components of Aurantii Fructus from different habitats were analyzed by gas phase ion mobility spectrometry, and the differences of volatile components in Aurantii Fructus from different habitats were analyzed by cluster analysis(CA), principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA).
RESULTS A total of 80 volatile compounds were detected, and 55 were identified qualitatively, including 13 terpenes, 18 aldehydes, 5 esters, 8 ketones, 8 alcohols, 2 acids and 1 pyrazine. The different origins of Aurantium Fructus could be distinguished by CA and PCA.
CONCLUSION The method is simple, economical and efficient, and can be used to identify and evaluate the types and differences of volatile organic compounds in Aurantii Fructus of different origins, providing references for the identification and quality control of Aurantii Fructus of different origins.
