Abstract The composition of the essential oils obtained from the flowers, leaves and stems of Artemisia campestris L. were analyzed by GC and GC/MS. Nineteen compounds representing 95.4% of the oil were identified in the flower oil, 22 compounds making up 90.3% of the oil were characterized in the oil obtained from leaves, and 14 compounds representing 96.7% of the stem oil of A. campestris were identified. Î±-Pinene (23.9%, 23.0% and 29.2%) and spathulenol (23.9%, 15.8% and 29.2%) were the main constituents in the flower, leaf and stem oils, respectively. The other main component of the flower oil was bicyclogermacrene (12.0%) and of the leaf oil Î²-pinene (12.6%). No significant difference was observed between compositions of flower, leaf and stem oils.
