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. -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 -pinene (12.6%). no significant difference was observed between compositions of flower, leaf and stem oils.
