Compositional Variability and Toxic Activity of Mugwort (Artemisia vulgaris) Essential Oils.
The compositional variability of the essential oils of aerial parts of mugwort (Artemisia vulgaris L.), collected from fifteen wild populations in Lithuania is detailed. The most predominant components were davanones (13.8-45.5%, six oils), germacrene D (9.1-30.5%, four oils), 1,8-cineole (16.4%, one oil), camphor (18.9%, one oil), trans-thujone (8.9 and 10.9%, two oils) and cis-chrysanthenyl acetate (10.4%, one oil). To the best of our knowledge, the davanone chemotype for A. vulgaris oils is described for the first time. The toxicity of the mugwort essential oils was determined using brine shrimp (Anemia sp.) assay. LC0 values (10.3-23.1 μg/mL) obtained for the oils after 24 h of exposure revealed that the oils containing appreciable amounts of germacrene D, 1,8-cineole, camphor and davanone were notably toxic.

Essential oil composition of Artemisia herba-alba from southern Tunisia.
The composition of the essential oil hydrodistilled from the aerial parts of 18 individual Artemisia herba-alba Asso. plants collected in southern Tunisia was determined by GC and GCMS analysis. The oil yield varied between 0.68% v/w and 1.93% v/w. One hundred components were identified, 21 of of which are reported for the first time in Artemisia herba-alba oil. The oil contained 10 components with percentages higher than 10%. The main components were cineole, thujones, chrysanthenone, camphor, borneol, chrysanthenyl acetate, sabinyl acetate, davana ethers and davanone. Twelve samples had monoterpenes as major components, three had sesquiterpenes as major components and the last three samples had approximately the same percentage of monoterpenes and sesquiterpenes. The chemical compositions revealed that ten samples had compositions similar to those of other Artemisia herba-alba essential oils analyzed in other countries. The remaining eight samples had an original chemical composition.
