Sažetak
The Croatian Adriatic coast and islands form a unique and distinctive area as a habitat for 80 Centaurea (Asteracea) taxa out of which 27 are endemics ; out of total 400- 700 species, distributed in 27 sections in this genus (1). Section Acrocentron, where both studied Centaurea salonitana L. and Centaurea rupestris L. belong, is one of the largest sections of Centaurea genus (2). There are some studies connecting the cell nuclei ploidy and variation in volatile oil composition implicating possible connection (3). The aim of the present study was to investigate the involvement of cell nuclei ploidy, determined using flow cytometry, in variation of essential oil composition in two species of Acrocentron section: C. salonitana and C. rupestris, from two different localities in Croatia, Adriatic region. The essential oil composition was determined using GC and GC-MS analysis of C. salonitana diploid and tetraploid and C. rupestris two diploid population’s essential oils. The diploid and tetraploid C. salonitana showed very similar composition of essential oils, number of determined components and yield of essential oil. There were more differences among two different species than the same species with different ploidy level. However when comparing two populations of the same species from different ecological conditions, such as continental and Mediterranean climate we have noticed there are differences among the essential oils of the same species from two different localities. The study presents the first results on C. salonitana essential oil composition, as well as first comparison of diploid and tetraploid population’s volatile oils.
