This study reports on the analysis of eleven Jarrah () honeys, of which nearly half (n = 5) were re-classified as Blackbutt () honey on the grounds of the predominant flower pollen identified by melissopalynology. Based on a comprehensive analysis of the honeys' physico- and phytochemical characteristics and antioxidant activity data, taking into account pH, electrical conductivity, refractive index and Brix values as well as moisture content, individual fructose and glucose content and derived fructose to glucose ratio alongside total phenolic content and antioxidant activity determined by the DPPH assay, no statistically significant difference was found amongst the eleven honeys classified by pollen analysis into two honey groups, 'Jarrah' or 'Blackbutt'. This study therefore draws into question the value of melissopalynology as an analysis tool to authenticate Jarrah honey.
本研究报告了对11种红柳桉蜂蜜的分析情况，其中近半数（n = 5）因通过蜂蜜花粉学鉴定出的主要花粉种类而被重新归类为桉木蜂蜜。基于对这些蜂蜜的物理化学特性及抗氧化活性数据的全面分析，同时考虑到pH值、电导率、折射率、波美度值以及水分含量、果糖和葡萄糖的个体含量及由此得出的果糖与葡萄糖比例，还有通过DPPH法测定的总酚含量和抗氧化活性，在通过花粉分析分为“红柳桉”或“桉木”两个蜂蜜组的这11种蜂蜜之间，未发现具有统计学意义的差异。因此，本研究对蜂蜜花粉学作为鉴定红柳桉蜂蜜的分析工具的价值提出了质疑。
