Abstract

The paper reports on the volatile components oil from aerial parts of two Asteraceae growing
wild in Croatia: Centaurea spinosociliata ssp. cristata (syn. Centaurea cristata Bartl. subsp. rabenhorstiana
(Sch.Bip.) Nyman) (CSC) and C. spinosociliata ssp. spinosociliata (CSS). The volatile components
were obtained by hydrodistillation from selected plants and were determined by the GC-MS system on
two fused-silica capillary columns of different polarity. The oil content was 0.08 % (CSC) and 0.07 %
(CSS) on a dry weight basis. Altogether 73 compounds were identified accounting for 90.8 % (CSC) and
92.8 % (CSS) of the total oil, that were characterized mainly by hydrocarbons (37.9 %; 30.4 %), sesquiterpene
hydrocarbons (14.1 %; 29.1 %), oxygenated sesquiterpenes (22.2 %; 13.1 %). The major components
of the samples were heptacosane (11.2 %; 12.6 %), cyclosativene (2.1 %; 6.4 %), caryophyllene
oxide (10.2 %; 4.7 %). Monoterpenes, fatty acids and phenolic compounds were absent or present in low
amount in both oils. The chemotaxonomy of the subgenus Acrolophus is briefly discussed.
