| Resumen en inglés | The essential oil isolated by hydrodistillation from flowers and root bark of Gochnatia polymorpha (Less) Cabr. ssp floccosa Cabr. (Asteraceae) was analyzed by capillary GC/MS. Thirty components were identified in oil of flowers. The composition depends on the stage of flowering. At the beginning of flowering, the main components were (E)-nerolidol (20,4%) and eugenol (17,9%) whereas at the end they were phenylacetaldehyde (14,6%) and tricosane (12,0%). In the essential oil of root bark ten sesquiterpenes were identified. The major components were beta-bisabolene (31,0%) and beta-bisabolol (21,5%). This paper describes for the first time the composition of essential oil in the genus Gochnatia |
