Essential oil studies in eight populations of Artemisia L. species in Azarbaijan-e-Gharbi, Iran

Considering Artemisia-Astragalus as the largest community in Iran, currently, basic studies are conducting on Artemisia spp. properties. Ecologic-systematical aspects of esantial oil studies of eight populations (six species) of the genus were dealt in Azarbaijan-e-Gharbi. In this study, generative browses containing flowers of different species/populations were gathered in the same phenological stage. After preparing dry matter of the browses in open air, water distillation applied for obtaining essential oils used for investigating constituents by GC and GC/MS. To conduct a comparison between different studied taxons, a cluster analysis was used in Minitab 11.12. The results showed that there were two different chemotypes of A. fragrans and the oil was free of common detected toxic components in A. absinthium.The resulted cluster proved the inefficiency of chemical data in systematical categorizing of different taxons even in subgenus levels.
