Abstract:

Glucosinolate and its degradation products in honey of Brassica napus L. were extracted using mixed organic solvents. These obtained products were subjected to quantitative examinations by palladium chloride method and further isolated and identified by gas chromatography-mass spectrometry (GC-MS). Results revealed that glucosinolate was observed in fresh honey of Brassica napus L., and isothiocyanate, one of degradation products of glucosinolate was detected in honey of Brassica napus L. during storage for half year at room temperature. Moreover, more glucosinolate in fresh honey of Brassica napus L. were degraded to form isothiocyanate with prolongation of storage.

Key words: honey of Brassica napus L, glucosinolate, isothiocyanate, degradation product, identification
