The chemical composition of essential oil of Anthemsmelampodinais determined by GC/MS. The oil was obtained by hydro-distillation and SPME extraction methodsIn the SPME method, a total of 41 constituents were identified monoterpene hydrocarbons (88.89%) were the main class of compounds detected in the SPME method with b-pinene(35.29%), trans-ocimene(23.96%) andterpinolene(15.78%) being detected as the main constituents. On the other hand, hydro-distilled oil was rich in oxygenated sesquiterpene(31.22%).
