摘要：

The leaf essential oil of Fleischmannia pratensis (Asteraceae) was obtained by hydrodistillation and analyzed by GC-MS. A total of 35 compounds were identified in the leaf oil (99.4% of the composition), which was dominated by the sesquiterpenes (E)-caryophyllene (26.1 %) and germacrene D (49.1 %). The essential oil was screened for antimicrobial activity against Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Aspergillus niger. E pratensis leaf oil only showed activity against Bacillus cereus (MIC = 39 mu g/mL).
