Essential oil composition of Centaurea kilaea flowers, stems and C. cuneifolia flowers were investigated by GC, GC/MS. Flowers and stems of C. kilaea afforded very low essential oil yield <0.01% (v/w). Nineteen and twenty compounds were identified in the flower and stem oils which represent 59.5% and 77.6% of the C. kilaea oil respectively. The main components of the C. kilaea flower oil were hexadecanoic acid 26.2%, tetradecanoic acid 18.1%, ?-Eudesmol 3.3% and decanoic acid 3.1%. The stem oil contains hexadecanoic acid 55.5% and ?-Eudesmol 3.2%. Flowers of C. cuneifolia afforded very low essential oil yield <0.01% (v/w). Twenty five compounds were identified in the flower oil of C. cuneifolia which represent 69.92% of the oil. The main components of this oil include hexadecanoic acid 32.9%, tetradecanoic acid 14.4%, heptacosane 6.1% and nonacosane 4.3%. Essential oils obtained from both species have saturated fatty acids and alkanes as the major components, but both oils also contain minor amounts of sesquiterpenes
