Abstract The flowering part of Artemisia khorassanica Podl. was collected from Khorassan province in Iran and hydrodistilled to produce a light-yellow oil at a yield of 0.06%. The oil was analyzed by GC and GC/MS. Twenty-seven compounds were identified, among which Î±-thujone (43.4%), Î²-thujone (16.2%) and camphor (12.6%) were the major constituents.
