Abstract

Cyanus Mill. genus, belonging to the Asteraceae family, includes more than 50 taxa, mainly growing in Central and Southern Europe, North Africa, Asia Minor, and the Caucasus. Previous investigations on Cyanus taxa have shown that they are rich source of flavonoids and phenolic compounds but, differently from species of genus Centaurea, almost devoid of sesquiterpene lactones. In the present study, the chemical composition of the essential oils from aerial parts of Cyanus adscendens (CA) and C. orbelicus (CO), collected in Bulgaria, and not previously investigated, was evaluated by GC-MS. The main components of CA were alpha-bergamotene (31.3%), (Z,Z,Z)-9,12,15-octadecatrien-1-ol (14.5%) and calarenepoxide (11.0%). Caryophyllene oxide (12.0%), together with alpha-cadinol (10.9%) and spathulenol (8.8%), were recognized as the main constituent of C. orbelicus EO. Furthermore, a complete review on the composition of all essential oils of the Cyanus taxa studied so far has been inserted and cluster analysis (PCA) was carried out.
