Abstract Essential oils from the leaves and flowers of Lantana camara L. var. aculeata were analyzed by GC and GC/MS. Thirty-nine and 46 constituents were identified in the leaf and flower oils, respectively. Sabinene (19.6â21.5%), 1,8-cineole (12.6â14.8%), Î²-caryophyllene (12.7â13.4%) and Î±-humulene (5.8â6.3%) were the major components of both oils. Two rare sesquiterpenoidsâhumulene epoxide III and 8-hydroxybicyclogermacreneâwere also isolated from the oils.
