Composition of Artemisia Annua Essential Oil Obtained from Species Growing Wild in Bulgaria

The Artemisia annua essential oil was obtained by hydro distillation of species growing wild in Bulgaria and was analyzed by GC/MS. Thirty six compounds were identified. The main ones were α-caryophillene (24.73%), α-cuvebene (13.53%), α-copaene (7.42%), α-selinene (8.21%) artemisia ketone (8.45%) and camphor (3.61%).
