Berg., (Myrtaceae) obtained by hydrodistillation, were analyzed by capillary GC and GC/MS. Thirty-four components were identified, representing more than 80% of total oil. The major components were β-caryophyllene (flowers −12.8%), caryophyllene oxide (stems—17.2%), globulol (stems—16.5%; leaves—22.5% at vegetative stage and 18.9% at flowering stage), 1-epi-cubenol (stems −10.9%), epi—α—muurolol (stems—16.8%) and α—cadinol (stems—12.1%; flowers −10.1%). The oils were evaluated against 20 strains of bacteria (Gram-positive and Gram-negative) and yeasts. All oils showed mild to moderate antimicrobial activity associated mainly with Gram-positive bacteria and yeasts.
