Compositional variability of mugwort ( Artemisia vulgaris L.) essential oils has been investigated in the study. Plant material (over ground parts at full flowering stage) was collected from forty‐four wild populations in Lithuania. The oils from aerial parts were obtained by hydrodistillation and analyzed by GC ( FID ) and GC / MS . In total, up to 111 components were determined in the oils. As the major constituents were found: sabinene, 1,8‐cineole, artemisia ketone, both thujone isomers, camphor, cis ‐chrysanthenyl acetate, davanone and davanone B. The compositional data were subjected to statistical analysis. The application of PCA (Principal Component Analysis) and AHC (Agglomerative Hierarchical Clustering) allowed grouping the oils into six clusters. AHC permitted to distinguish an artemisia ketone chemotype, which, to the best of our knowledge, is very scarce. Additionally, two rare cis ‐chrysanthenyl acetate and sabinene oil types were determined for the plants growing in Lithuania. Besides, davanone was found for the first time as a principal component in mugwort oils. The performed study revealed significant chemical polymorphism of essential oils in mugwort plants native to Lithuania; it has expanded our chemotaxonomic knowledge both of A. vulgaris species and Artemisia genus.
