Samples of unifloral sulla (Hedysarum coronarum L.) honey from Sardinia (Italy) were analysed. To investigate the chemical composition of the honey volatiles two solvent systems were used for ultrasonic solvent extraction (USE): 1) a 1:2 (v/v) pentane and diethyl ether mixture and 2) dichloromethane. All the extracts were analysed by GC and GC/MS. These procedures have permitted the identification of 56 compounds that include norisoprenoids, benzene derivatives, aliphatic compounds and Maillard reaction products. Norisoprenoids were the major compounds in both extracts, dominated by vomifoliol (5.3-11.2%; 9.6-14.0%) followed by minor percentages of other norisoprenoids such as α-isophorone, 4-ketoisophorone, 3-oxo-α-ionol or 3-oxo-α-ionone. Other abundant single compounds in the extracts were 3-hydroxy-4-phenylbutan-2-one (0.8-5.4%; 0.6-5.7%) and methyl syringate (3.0-5.7%; 2.2-4.1%). The composition of the volatiles and semi-volatiles in the obtained extracts suggests that sulla honey is quite distinctive relative to the other honeys that have been chemically studied by GC/MS, but no specific markers of the honey botanical origin were found.
对来自意大利撒丁岛的单花沙巴槐（Hedysarum coronarum L.）蜂蜜样本进行了分析。为了研究蜂蜜挥发性成分的化学组成，使用了两种溶剂系统进行超声溶剂萃取（USE）：1）正戊烷和二乙醚的 1:2（v/v）混合物和 2）二氯甲烷。所有提取物均通过 GC 和 GC/MS 进行分析。这些程序允许鉴定出 56 种化合物，包括类异戊二烯、苯衍生物、脂肪族化合物和美拉德反应产物。类异戊二烯是两种提取物中的主要化合物，以vomifoliol（5.3-11.2%；9.6-14.0%）为主，其次是其他类异戊二烯如α-异佛尔酮、4-酮异佛尔酮、3-氧-α-依兰醇或 3-氧-α-依兰酮的含量较低。提取物中其他丰富的单一化合物为 3-羟基-4-苯基-2-丁酮（0.8-5.4%；0.6-5.7%）和甲基丁香酸酯（3.0-5.7%；2.2-4.1%）。获得的提取物中挥发性和半挥发性成分的组成表明，与其他通过 GC/MS 进行了化学研究的蜂蜜相比，沙巴槐蜂蜜具有相当独特的特征，但未发现蜂蜜植物来源的特定标志物。
