The aim of this work was to give characteristic stable carbon and nitrogen isotope ratio (C, C and N) ranges and examine their relation with botanical origin of honey. Despite that C parameter has primary purpose to detect honey adulteration, stable isotopes generally have become important parameter for detection its botanical and geographical origin. The data about stable isotopes are scarce in comparison to other well-known parameters in honey, and in Croatia there is no data about stable isotopes in unifloral honey. This research includes six characteristic honey types (black locust, chestnut, lime, rape, winter savory, and sage honey) from Croatia. Large number of differences between honey types were found in the analyzed IRMS parameters. PCA analysis has successfully separated winter savory from all other honey types, except sage honey, whose samples differed from black locust samples.

本研究的目的是给出特征性的稳定碳氮同位素比值（碳-13、碳-12和氮-15）范围，并研究它们与蜂蜜植物来源的关系。尽管碳-13参数的主要目的是检测蜂蜜掺假，但稳定同位素通常已成为检测蜂蜜植物和地理来源的重要参数。与蜂蜜中其他知名参数相比，关于稳定同位素的数据较少，在克罗地亚，关于单花蜂蜜中稳定同位素的数据也没有。本研究包括来自克罗地亚的六种特色蜂蜜类型（刺槐蜜、板栗蜜、椴树蜜、油菜花蜜、冬香薄荷蜜和鼠尾草蜜）。在分析的同位素比率质谱仪参数中发现了蜂蜜类型之间的大量差异。主成分分析已成功地将冬香薄荷蜜与所有其他蜂蜜类型区分开来，但鼠尾草蜜除外，其样本与刺槐蜜样本不同。
