在这项研究中，与许多与欧洲蜜蜂一起进化的其他植物物种相比，西澳大利亚州的eucalmont花粉的脂质水平较低（0.59-1.9%）。花粉脂肪中亚油酸占优势（35.7-48%）。脂肪酸组成中，肉豆蔻酸、棕榈酸、硬脂酸、油酸、亚麻酸和花生酸占绝对优势，亚油酸的平均含量为2.77-5.81 mg/g花粉。这些结果可能对澳大利亚养蜂业在完善疾病管理策略方面具有重要意义，因为其他研究人员已经发现，2种经济上具有破坏性的蜜蜂疾病（EFB和AFB）可以通过一定浓度的酸来抑制。与其他研究的桉树相比，红桉树或marri（Corymbia calophylla）花粉脂质也主要由2种其他已知的抗菌脂肪酸：肉豆蔻酸（0.25 mg/g花粉）和亚麻酸（1.06 mg/g花粉）。
Western Australian eucalypt pollens in this research have low levels of lipid (0.59-1.9%) when compared with many other plant species that have evolved alongside the European honeybee. Eucalypt-pollen lipid was dominant in linoleic acid (35.7-48%). The six other major fatty acids that were present in the lipid were myristic, palmitic, stearic, oleic, linolenic and arachidic acids.Linoleic acid was dominant in eucalypt pollen at average concentrations of 2.77-5.81 mg/g pollen. These results could be of significance to the Australian beekeeping industry in refining disease-management strategies in the light that other researchers have found that 2 economically damaging bee diseases (EFB and AFB) are inhibited by certain concentrations of the acid. Redgum- or marri (Corymbia calophylla)-pollen lipid was also dominated by 2 other known antibacterial fatty acids: myristic (0.25 mg/g pollen) and linolenic (1.06 mg/g pollen), when compared with the other eucalypts studied.
