Chemical Composition of the Essential Oils Obtained From the Flower, Leaf and Stem of Artemisia campestris L. From Iran

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 stern oil of A. campestris were identified. alpha-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 beta-pinene (12.6%). No significant difference was observed between compositions of flower, leaf and stem oils.
