Abstract: In order to label the botanical and geographical origin of unioral rape honey and discriminate adulterated rape honey, the volatile components in 49 rape honey samples from different geographical origins were analyzed by ultrasonic-assisted extraction, gas chromatography with flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) and fingerprinted. The results indicated that 49 samples investigated could be assigned into 5 groups, with an effective discrimination between raw and commercial rape honeys. Both rape honeys exhibited an obvious difference in their volatile components. We deduce that benzoic acid-4-hydroxy-3,5-dimethoxy-hydrazide has the potential to be used as a marker of botanical origin of rape honey.

Key words: rape honey, ultrasonic-assisted solvent extraction (USE), gas chromatography-mass spectrometry (GC-MS), fingerprint
