Abstract The chemical composition of 12 essential oil samples of the aerial parts of two flower color types of Lantana camara from Madagascar collected each month of the year, have been characterized by GC and GC/MS. The main components changed within the two flower color types. The pink-violet flower type contained mainly davanone (23.5%), β-caryophyllene (11.7%), sabinene (10.4%), linalool (5.9%) and α-humulene (4.7%), while the main components of the yellow-orange type were β-caryophyllene (29.8%), β-bisabolene (15.3%), sabinene (13.3%), γ-cadinene (3.7%) and α-humulene (3.1%).
