Abstract The essential oils isolated from the fresh leaves of Eugenia pitanga cultivated in Arizona, from seed originally collected in Paraguay, were analyzed by GC and GC/MS. The major components of the oil were (E)-β-ocimene (24.1±3.2%), germacrene D (20.8±2.4%), bicyclogermacrene (10.9±1.4%), and (Z)-β-ocimene (10.4±1.4%)
