Essential oil composition of two Centaurea L. (Asteraceae) species from Turkey.

Abstract

In this study, aerial parts of C. cynaus L. and C. depressa Bieb. were analysed by HS-SPME/GC-MS. As a result thirty five and thirty seven components were identified representing 92.3% and 91.1% of the oil, respectively. Germacrene D (14.8%), caryophyllene oxide (19.6%) and butanal (8.7%) were detected the main compounds of C. cynaus, however germacrene D (20.6%), caryophyllene oxide (13.3%) and -eudesmol (12.6%) were detected the major constituents of C. depressa.
