Abstract The freshly distilled essential oil from the leaves of Eucalyptus camaldulensis collected in Tampa, FL, were analyzed by GC/MS. The major constituents identified in the oil included p-cymene (35.0%), ciyptone (13.7%), terpinen-4-ol (5.7%), spathulenol (4.3%), and cuminaldehyde (3.7%). Relatively a very low amount of 1,8-cineole (2.7%) was found. The oil was not typical in chemical composition of the high cineole types of this species most often referenced in the literature and was found to be one of the highest cryptone containing essential oils yet reported.
