Air‐dried leaves of Chuquiraga spinosa (R. et P.) D. Don (Asteraceae) gave by hydrodistillation a 0.2% yield of essential oil. The oil composition was analysed by GC and GC‐MS; 70 components were identified. The oil contained more than 76% of oxygen‐containing compounds. Carbonyl compounds were the most abundant components (36.1%) with p ‐methoxyacetophenone (8.6%) and p ‐hydroxyacetophenone (5.8%) as the main components of this group. β‐Humulene (3.4%) ar ‐curcumene (2.8%) and cuparene (2.5%) were the main sesquiterpene hydrocarbons. Spathulenol (3.8%) was the principal oxygenated sesquiterpene. Apiol (9.8%) was the most abundant phenylpropanoid derivative.
