采用气相色谱-质谱联用技术对巴西尤金、金银花尤金和蝴蝶花尤金叶片的精油进行了分析。巴西油树油中主要化合物为鸡皮酚（12.6%）和-二酚（8.7%），金莲油树油中主要化合物为-石竹烯（8.0%）和双环革烯（7.2%），伞花油树油中主要化合物为绿花酚（17.7%）和-蒎烯（13.2%）。测定了这些精油对金黄色葡萄球菌、铜绿假单胞菌和大肠杆菌的抑菌活性。所有精油均表现出从中等到较强的抑菌活性，其中以大花菊和巴西菊精油的抑菌活性最强，对金黄色葡萄球菌的抑制作用最强，其MIC值分别为119.2和156.2 μ g/mL。
The essential oils of the leaves of Eugenia brasiliensis, Eugenia beaurepaireana, and Eugenia umbelliflora were analyzed by GC-MS. The major compounds found in the oil of E. brasiliensis were spathulenol (12.6%) and tau-cadinol (8.7%), of E. beaurepaireana were beta-caryophyllene (8.0%) and bicyclogermacrene (7.2%), and of E. umbelliflora were viridiflorol (17.7%) and beta-pinene (13.2%). These oils were assayed to determine their antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. All of the oils analyzed showed antibacterial activity, ranging from moderate to strong, which was most accentuated for the E. umbelliflora and E. brasiliensis oils, which strongly inhibited the growth of S. aureus giving values of MIC = 119.2 and 156.2 mu g/mL, respectively.
