Headspace solid-phase microextraction (HS-SPME; PDMS/DVB fibre) and ultrasonic solvent extraction (USE; solvent A: pentane and diethyl ether (1:2 v/v), solvent B: dichloromethane) followed by gas chromatography and mass spectrometry (GC, GC-MS) were used for the analysis of Prunus mahaleb L. honey samples. Screening was focused toward chemical composition of natural organic volatiles to determine if it is useful as a method of determining honey-sourcing. A total of 34 compounds were identified in the headspace and 49 in the extracts that included terpenes, norisoprenoids and benzene derivatives, followed by minor percentages of aliphatic compounds and furan derivatives. High vomifoliol percentages (10.7%-24.2%) in both extracts (dominant in solvent B) and coumarin (0.3%-2.4%) from the extracts (more abundant in solvent A) and headspace (0.9%-1.8%) were considered characteristic for P. mahaleb honey and highlighted as potential nonspecific biomarkers of the honey's botanical origin. In addition, comparison with P. mahaleb flowers, leaves, bark and wood volatiles from our previous research revealed common compounds among norisoprenoids and benzene derivatives.
采用顶空固相微萃取（HS-SPME；PDMS/DVB 纤维）和超声溶剂萃取（USE；溶剂 A：戊烷和二乙醚（1:2 v/v），溶剂 B：二氯甲烷），结合气相色谱和质谱（GC、GC-MS）分析李属欧洲甜樱桃蜂蜜样品。筛选重点是天然有机挥发物的化学成分，以确定其是否可用作确定蜂蜜来源的方法。在顶空和提取物中共鉴定出 34 种化合物，包括萜烯、异戊二烯类和苯衍生物，其次是少量的脂肪族化合物和呋喃衍生物。两种提取物（溶剂 B 中占主导地位）中均含有较高比例的vomifoliol（10.7%-24.2%），以及从提取物（溶剂 A 中含量更丰富）和顶空（0.9%-1.8%）中提取出的香豆素（0.3%-2.4%），这些都被认为是李属欧洲甜樱桃蜂蜜的特征，并被突出为蜂蜜植物来源的潜在非特异性生物标志物。此外，与我们之前研究中李属欧洲甜樱桃花、叶、树皮和木材的挥发性成分进行比较，发现异戊二烯类和苯衍生物中有共同的化合物。
