Essential Oil Composition of Three Centaurea Species from Turkey: Centaurea aggregata Fisch. & Mey. ex. DC. subsp. aggregata , C. balsamita Lam. and C. behen L.

摘要

The essential oils of Centaurea aggregata subsp. a ggregata , C. balsamita and C. behen collected in the same habitat from Turkey, have been investigated. A total of 26, 54 and 26 components were identified in C. aggregata subsp. aggregata, C. balsamita and C. behen , respectively. The main constituents of the investigated populations of the three taxa have been revealed as follows: Centaurea aggregata subsp. aggregata: hexadecanoic acid (35.8%), phytol (7.2%), caryophyllene oxide(6.0%), spathulenol (6.0%); C. balsamita : hexadecanoic acid (23.0%), spathulenol (8.9%), germacrene D (2.1%); C. behen : hexadecanoic acid (32.7%), germacrene D (14.8%), and phytol (12.3%).
