摘要:

对油菜蜜中的硫代葡萄糖甙及其降解产物进行提取与定性分析。通过有机溶剂对油菜蜜中的硫代葡萄糖甙及其降解产物进行萃取,然后进行氯化钯显色反应,并采用气相色谱-质谱联用技术对硫代葡萄糖甙及其降解产物进行分离鉴定。结果表明新鲜的油菜蜜含有硫代葡萄糖甙,放置半年后油菜蜜中含有硫代葡萄糖甙的降解产物——异硫氰酸酯。随储藏时间的延长,新鲜的油菜蜜中的硫代葡萄糖甙会降解成异硫氰酸酯。

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
