【 摘 要 】

Aerial parts ofElyonurus muticus were collected in the four seasons of the year in theBrazilian Pantanal and subjected to extractrion with cold ethanol and to hydrodistillation.Sesquiterpenoids (E)-caryophyllene, bicyclogermacrene, spathulenol and caryophylleneoxide were the main components identified in the essential oils and their concentrationsvaried according to the plant collection period. The essential oils and theethanolic crude extracts were active against Bacillus cereus MIP 96016,Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC25923 and were not active against Escherichia coli ATCC 25922. The antibacterialactivities varied according to the plant collection period.
