A rare sample of maple (Acer spp.) honey from Croatia was analysed. Ultrasonic solvent extraction (USE) using: 1) pentane, 2) diethyl ether, 3) a mixture of pentane and diethyl ether (1:2 v/v) and 4) dichloromethane as solvents was applied. All the extracts were analysed by GC and GC/MS. The most representative extracts were 3) and 4). Syringaldehyde was the most striking compound, being dominant in the extracts 2), 3) and 4) with percentages 34.5%, 33.1% and 35.9%, respectively. In comparison to USE results of other single Croatian tree honey samples (Robinia pseudoacacia L. nectar honey, Salix spp. nectar and honeydew honeys, Quercus frainetto Ten. honeydew as well as Abies alba Mill. and Picea abies L. honeydew) and literature data the presence of syringaldehyde, previously identified in maple sap and syrup, can be pointed out as a distinct characteristic of the Acer spp. honey sample. Headspace solid-phase microextraction (HS-SPME) combined with GC and GC/MS identified benzaldehyde (16.5%), trans-linalool oxide (20.5%) and 2-phenylethanol (14.9%) as the major compounds that are common in different honey headspace compositions.
对来自克罗地亚的罕见枫糖（Acer spp.）蜂蜜样本进行了分析。采用超声溶剂萃取（USE）法，分别使用：1）戊烷、2）二乙醚、3）戊烷和二乙醚的混合物（1:2 v/v）和 4）二氯甲烷作为溶剂。所有提取物均通过 GC 和 GC/MS 进行分析。最具代表性的提取物是 3）和 4）。丁香醛是最显著的化合物，在提取物 2）、3）和 4）中分别占 34.5%、33.1%和 35.9%。与其他单一克罗地亚树蜜样本（洋槐蜜、柳属花蜜和蜜露蜜、栓皮栎蜜以及白云杉和欧洲云杉蜜露）的 USE 结果和文献数据相比，可以指出丁香醛的存在，此前在枫糖浆和枫汁中已被鉴定出来，这可以作为 Acer spp. 蜂蜜样本的一个显著特征。顶空固相微萃取（HS-SPME）结合 GC 和 GC/MS 鉴定出苯甲醛（16.5%）、反式芳樟醇氧化物（20.5%）和 2-苯乙醇（14.9%）是不同蜂蜜顶空成分中常见的主要化合物。
