Sažetak
Fucus virsoides J. Agardh (family Fucaceae, order Fucales) is known as an endemic brown macroalga distributed in the mediolittoral zones on rocky sheltered or moderately exposed shores only in the Adriatic Sea. In the previous reports it has been stated that this alga can be a potential source of polyunsaturated fatty acids and fucoxanthin that are known compounds with certain biological activities. This study encompasses the analysis of volatilome profile of fresh samples of F. virsoides obtained by headspace solid-phase microextraction, along with the determination of fatty acid composition and fucoxanthin content. The headspace composition of fresh F. virsoides revealed the dominance of pentadecane followed by pentadec-1-ene. The main fatty acid was oleic acid, followed by arachidonic acid and myristic acid. The significant amounts of ω3 and ω6 fatty acids were observed where eicosapentaenoic acid was the dominant ω3, while arachidonic acid was found as the major ω6 fatty acid. The fucoxanthin content determined in methanolic fraction F3 was 79.30±10.29 mg/100 g and it represented the main peak found in chromatographic analysis. Since macroalgae represent a valuable source of various bioactive compounds it is important to investigate their chemical profiles that will lead to the better understanding of marine algal biodiversity in the Adriatic Sea. The seasonal variations, differences in geographic locations and species- inherent characteristics can have an influence on the volatile compounds, fatty acids and fucoxanthin contents and further exploration is necessary.
