DLLME-gas chromatography-quadrupole time-of-flight mass spectrometry for classification of botanical origin of Chinese honey by its volatile and semi-volatile compound profile

摘要

A DLLEM combined with GC-QTOF method for profiling of Chinese honey from various botanical origins has been developed; The acquired data have been subjected to chemometric analysis using MPP, and principle components analysis has shown excellent separation among four groups of honey samples; The data analyzed by GC-QTOF can provide rich information on both volatile and semi-volatile compounds in honey; It is a potential and promising method for the discrimination and classification of Chinese honey from various botanical origins.
