The leaf-essential oil from Eucalyptus robusta and E. saligna, the latter in two phenologic stages, were analysed by gas chromatography coupled to mass spectrometry (GC-MS). The major constituent in E. robusta oil was the monoterpene alpha-pinene (73.0% of the total amount). The oil composition of the E. saligna was dependent of the phenologic stage. In the vegetative phase, the major constituents were p-cymene (54.2%) and gamma-terpinene (43.8%), while during the blossoming alpha-pinene became the major constituent followed by p-cymene (22.5%). Additionally, the antimicrobial activity for all three oils was evaluated against Staphylococcus aureus, Escherichia coli and Candida albicans. The E. robusta oil presented the highest growth inhibition for all the microorganisms tested.
对大叶桉和柳叶桉（后者处于两个物候阶段）的叶精油进行了气相色谱-质谱联用（GC-MS）分析。大叶桉油中的主要成分是单萜α-蒎烯（占总量的73.0%）。柳叶桉的油成分取决于物候阶段。在营养阶段，主要成分是对伞花烃（54.2%）和γ-萜品烯（43.8%），而在开花期，α-蒎烯成为主要成分，其次是对伞花烃（22.5%）。此外，还评估了这三种油对金黄色葡萄球菌、大肠杆菌和白色念珠菌的抗菌活性。大叶桉油对所有测试微生物的生长抑制作用最强。
