Essential oil composition of two endemic Centaurea species from Turkey

Abstract

Essential oil composition of Centaurea austroanatolica Hub.-Mor. and Centaurea kizildaghensis Uzunh., E. Doğan & H. Duman were analyzed by means of gas chromatography-mass spectrometry (GC-MS). Sixty and fourty six compounds were identified in the essential oils of C. austroanatolica and C. kizildaghensis, respectively. The major components were determined hexadecanoic acid (21.3%), caryophyllene oxide (4.8%), dodecanoic acid (4.2%) and heptacosane (3.5%) in C. austroanatolica oil, hexadecanoic acid (24.4%), phytol (9.3%), caryophyllene oxide (3.8%) and salvial-4(14)-en-1-one (3.1%) in C. kizildaghensis oil.
