Abstract The essential oil from the aerial parts of Telekia speciosa (Schreb.) Baumg. obtained by hydrodistillation was analyzed by GC and GC/MS. One hundred and eighty constituents identified accounted for 86.4% of the total oil. The major components of the oil were: (E,Z)-farnesol (12.0%), (E)-nerolidol (10.2%), b-caryophyllene (5.4%), caryophyllene oxide (4.5%), intermedeol (4.2%) and alantolactone (4.1%). The terpenoid fraction represented more than four-fifths of the oil (15.9% monoterpenoids, 64.7% sesquiterpenoids, both classes dominated by oxygenated derivatives). Unlike the root oil, where the eudesmanes were by far the most dominant compound class, the volatiles of the aerial parts were mainly consisted of acyclic-farnesane sesquiterpenoids (26.2%), along side with caryophyl-lanes (11.6%) and eudesmanes (14.5%).
