ABSTRACT:The chemical composition of the essential oil obtained from two subspecies of Clinopodium axillare growing wild in the High Valley Region of Bolivia, Province of Cochabamba, was determined by a combination of GC and GC/MS measurements. It is dominated by oxygenated monoterpenes. Piperitenone oxide (20-30 %), piperitone epoxide (15-19 %), piperitenone (13 %), pulegone (3-5 %) and piperitone (4-5 %) as well as limonene (8-12 %) and -pinene (1-5 %) are the major constituents. These results, in conjunction with a recent description of the genus Clinopodium, provide a better understanding of the classification of this plant.
