Abstract
Crni jasen (Fraxinus ornus L.) je bjelogorično stablo ili grm iz porodice maslina, Oleaceae. U ovom završnom radu određen je sastav i sadržaj hlapljivih spojeva cvijeta crnog jasena. Za izolaciju hlapljivih spojeva korištena je vodena destilacija u modificiranoj aparaturi po Clevengeru i mikroekstrakcija vršnih para na čvrstoj fazi korištenjem različitih vlakna. Analiza svih uzoraka provedena je vezanim sustavom plinska kromatografija - spektrometrija masa na HP-5MS koloni. Glavni sastojci eteričnog ulja su ravnolančani zasićeni ugljikovodici dokosan (C 22 H 46 ) i trikosan (C 23 H 48 ). Glavni spoj dobiven mikroekstrakcijom vršnih para na oba vlakna bio je seskviterpen α-farnezen. Kvantitativno značajan spoj izoliran na sivom vlaknu je triterpenoid skvalen, dok je na plavom vlaknu pronađen ester etil- benzoat.
Abstract (english)
Manna ash (Fraxinus ornus L.) is a deciduous tree or shrub from the olive family, Oleaceae. In this bachelor's thesis the composition and content of volatile compounds of manna ash flowers were determined. Hydrodistillation in modified Clevenger-apparatus and headspace solid phase microextraction (with various fibres) were used for the isolation of volatile compounds. Analysis of all samples was carried out by gas chromatography-mass spectrometry (GC/MS) on an HP-5MS column. The main constituents of essential oil were straight chained alkanes docosane (C 22 H 46 ) and tricosane (C 23 H 48 ). The main compound obtained by headspace microextraction was sesquiterpene α-farnesene on both fibres. Quantitatively significant compound isolated on the gray fiber, was the triterpenoid squalene, while on the blue fiber, the esther ethyl benzoate was found.
