摘要: 分析油菜单花蜜中的挥发性成分,建立油菜单花蜜挥发性成分的指纹图谱。采用超声波辅助萃取法提取49种不同产地的油菜单花蜜中的挥发性物质,并利用气相-氢火焰化离子检测(gas chromatography-flame ionization detector,GC-FID)和气相色谱-质谱联用(gas chromatography-mass spectrometry,GC-MS)技术分析,对气相分析结果进行聚类分析和相似度分析。结果表明:49种油菜蜜分为5类,能明显区分未经加工的原料油菜蜜和市售油菜蜜;原料油菜蜜和市售油菜蜜的挥发性成分存在明显差异;推断苯甲酸-4-羟基-3,5-二甲氧基-酰肼可能作为油菜蜜植物源标记物。

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
