Sažetak
The composition of volatile organic compounds (VOCs) of fresh flowering heads (capitula) of Centaurea spinosociliata Seenus (Asteraceae, Circum-Mediterranean clade – CMC, subsect. Centaurea) from Otrić, Croatia was analyzed. Plant material was collected in August 2021, and flowering heads were frozen until extraction. The essential oil was obtained by simultaneous distillation and extraction using Likens–Nickerson type apparatus and analyzed by GC-FID/GC-MS. In total, 41 compounds were identified out of 45 detected, representing 91.11% of the total VOCs content. Peaks that were lower than 0.1% were not included. Sesquiterpenes were the most represented class of compounds (65.13%), with sesquiterpene hydrocarbons being more abundant (39.91%) than oxygenated sesquiterpenes (25.22%). Aliphatic compounds were also present in high amount (30.96%), while monoterpenes were the least abundant, with α-pinene detected only (0.13%). Germacrene D was identified as a principal compound (11.65%), followed by caryophyllene oxide (10.32%) and hexanal (7.64%). The essential oil composition of C. spinosociliata was previously investigated, and a few differences were noted when compared to the results of the current study. Taxonomic implications are further discussed.
