Óleo essencial de Gochnatia polymorpha (Less) Cabr. ssp floccosa Cabr.

Óleo essencial de Gochnatia polymorpha (Less) Cabr. ssp floccosa Cabr.

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.
