✦ Synopsis

Air-dried leaves of Chuquiragu spinosu (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 YO) with p-methoxyacetophenone (8.6%) and p-hydroxyacetophenone (5.8%) as the main components of this group. b-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(9.89'0) was the most abundant phenylpropanoid derivative.
