Abstract
Sažetak Razvijena je i validirana metoda istodobnog određivanja 31 polifenola i indol-3-octene kiseline u vinu tekućinskom kromatografijom visoke djelotvornosti uz primjenu detektora s nizom dioda i fluorescencijskog detektora. Optimirani su uvjeti ekstrakcije pojedinačnih polifenolnih sastavnica i indol-3-octene kiseline na kopolimernom sorbensu N-vinilpirolidon-divinilbenzenu. U bijelim i crnim vinima iz Hrvatske utvrđeni su sastav i masene koncentracije polifenola i indol-3-octene kiseline. Po prvi puta određene su masene koncentracije indol-3-octene kiseline u crnim vinima iz Hrvatske, koje su bile od 0,076 mg L-1 do 1,031 mg L-1. Za autohtone hrvatske kultivare Teran i Plavac mali uočen je kemotaksonomijski uzorak za antocijane i njihove acilne oblike. Uspoređene su i optimirane dvije tehnike ekstrakcije 2-aminoacetofenona iz vina, spoja odgovornog za netipičnu aromu bijelih vina: mikroekstrakcija na čvrstoj fazi izravnim uranjanjem vlakna u uzorak vina i mikroekstrakcija na čvrstoj fazi iz para iznad otopine pomognuta ultrazvukom. Kvalitativna i kvantitativna analiza 2-aminoacetofenona provedena je plinskom kromatografijom uz spektrometar masa kao detektor.
Abstract (english)
Method for determination of 31 polyphenols and indole-3-acetic acid in wines was developed using high performance liquid chromatography with diode array detector and fluorescence detector. Solid phase extraction of polyphenolic compounds and indole-3-acetic acid using N-vinylpirolidone-divinylbenzene copolymer as sorbent was optimized. Polyphenolic composition and indole-3-acetic acid were determined in white and red wines from Croatia. Indole-3-acetic acid was determined for the first time in red wines from Croatia, in mass concentrations ranging from 0.076 mg L-1 to 1.031 mg L-1. Anthocyanins pattern as chemotaxonomic marker was observed for autochtonic cultivars Teran and Plavac mali from Croatia. Ultrasound-assisted headspace solid-phase microextraction and direct immersion solid-phase microextraction were compared and optimized for etermination of 2-aminoacetophenone. Identification and quantification of 2-aminoacetophenone was performed by gas chromatography-mass spectrometry.
