The essential oil (hydrodistillation) from the aerial parts of Artemisia rutifolia from two different regions of Tajikistan were dominated by α-thujone (20.9% and 36.6%) and β-thujone (47.3% and 36.1%) with lesser amounts of 1,8-cineole (3.2% and 11.7%) and germacrene D (2.8% and 1.8%). \\

Essential oils of Artemisia rutifolia can be divided into “Tajik” (prevalence of α- and β-thujone) and “Buryat-Mongol” (prevalence of benzylacetone and camphor) chemotypes. \\

Essential oil of A. rutifolia was obtained from samples collected in the Middle Gobi province of Mongolia. "Particular attention was devoted to the identification of the minor phenylbutanoids and a preliminary determination of the main contributors to the odor of the oil. Hence, the essential oil was fractionated by column chromatography and subjected to GC-MS/FID and GC-O/FID analyses. Camphor, 1,8-cineole, and 4-phenylbutan-2-one were identified as the dominant compounds, the latter being the main odorant responsible for the typical fresh-fruity smell of the plant. Moreover, α- and β-thujones were absent, and seven previously unreported 4-phenylbut-2-yl esters were unambiguously identified through combinatorial synthesis." \\
