Özet
The genus Centaurea L. (Asteraceae) is represented in Turkey with 192 taxa, 114 of which are endemic (1–4). The present study aims at investigating the volatile compounds of two endemic Centaurea species ( C. aphrodisea Boiss. and C. polyclada DC.) and three widespread ( C. athoa DC., C. hyalolepis Boiss. and C. iberica Trev. ex Sprengel) Centaurea taxa from Turkey by GC and GC/MS. The analyses revealed 109 constituents, accounting between 87% and 93.4% of the oils. Major constituents of the oils of Centaurea were as follows; in C. aphrodisea : spathulenol (8.1%) and hexahydrofarnesyl acetone (7.8%); in C. athoa : caryophyllene oxide (17.1%) and heptacosane (8.1%); in C. iberica ; hexadecanoic acid (27.9%) and cyclosativene (13%); in Centaurea hyalolepis : hexadecanoic acid (8.2%) and phytol (5.6%) and in C. polyclada : hexadecanoic acid (8.1%) and hexahydrofarnesyl acetone (7.1%).
