AB  - In this study, we estimated the usage of Cabernet Sauvignon in microvinifications, obtaining wines with increased phenolic compound content. Kinetic extraction of phenolic compounds during alcoholic fermentation was affected by maceration time (3, 5, 7, 14 and 21 days) and the addition and kinetics of enzyme preparations (EP). The highest extraction rates were observed for catechin (EXV EP – EXV enzyme preparation and CP EP – Color plus enzyme preparation) and p-hydroxybenzoic acid (Car EP - Caractere enzyme preparation). According to extraction time of the analyzed phenolic compounds, maximal values (ellagic acid, ferulic acid, chlorogenic acid, caffeic acid, naringenin, p-hydroxybenzoic acid, p-coumaric acid, protocatechuic acid, trans-resveratrol, syringic acid, vanillin, and vanillic acid) were obtained on day 15 of maceration with addition of CP EP, with exceptions of gallic acid, catechin, and myricetin. Prolonged maceration times, up to 21 days, showed the most potent DPPH free radical scavenging activity with Car EP and the highest Ferric Reducing Ability of Plasma (FRAP) values with CP EP.
AB  - Во ова истражување беше применета микровинификација на грозје од сортата каберне совињон и беа добиени вина со зголемена содржина на фенолни соединенија. Беше забележано дека кинетичката екстракција на фенолните соединенија во текот на алкохолната ферментација зависи од времето на мацерација (3, 5, 7, 14 и 21 ден) и од додавањето и кинетиката на ензимските препарати (EP). Најголема екстракција беше забележана за катехин (EXV EP – комерцијален ензимски препарат и CP EP – ензимски препарат) и p-хидроксибензоева киселина (Car EP – ензимски препарат Caractere). Во однос на влијанието на времето на екстракција врз анализираните фенолни соединенија (елагова киселина, ферулна киселина, хлорогенска киселина, кофеинска киселина, нарингенин, p-хидроксибензоева киселина, p-кумарна киселина, протокатехинска киселина, trans-ресвератрол, сирингинска киселина, ванилин и ванилна киселина), максимални вредности се добиени петнаесеттиот ден од мацерација со додавање на CP EP, со исклучок на гална киселина, катехин и мирицетин. Продолженото време на мацерација до 21 ден доведе до највисока антиоксидантна активност одредена со методите DPPH и FRAP, кај вината со Car EP и CP EP.

AB  - This study aimed to estimate the potential of the selected berry (strawberry) and drupe (apricot, plum and sweet cherry) fruits as the substrates for the production of new fruit wines enriched with phenolic compounds. Sweet cherry wine (cultivar Burlat) stood out both for the profound content of phenolics (followed by their chemical profile) and potent anti-DPPH radical activity. The same fruit wine samples exhibited high redox potentials, slightly lower than strawberry and plum wine samples. Therefore, sweet cherry cultivar Burlat may be well recommended for development of novel fruit-based products endowed with naturally occurring phenolics. In any case, the remaining four cultivars are also worth further research efforts, particularly apricot cultivar Keckemetska ruza, which is one of the representatives of greatly underestimated fruit type thus far as a substrate for the production of the relevant fruit wines.

AB  - Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the compound and an easy way of including resveratrol in the human diet. In this study, the most popular commercial Serbian wines (red, white and rose-type) were analyzed for their content of trans- and cis-resveratrol. The analysis was performed by HPLC with a UV detector. Prior to the injection, phenolic compounds were extracted onto a LiChrolut RP18 bonded silica cartridge. The concentration of trans-resveratrol ranged from 0.11 to 1.69 mg L-1 and cis-resveratrol from 0.12 to 1.49 mg L-1.
AB  - Metodom tečne hromatografije (HPLC) ispitan je sadržaj slobodnog oblika trans- i cis-rezveratrola u osamnaest komercijalnih uzoraka (10 crvenih, 7 belih i 1 roze) srpskih vina. Svi uzorci su pre hromatografije ekstrahovani SPE tehnikom na LiChrolut RP18 koloni. trans-Rezveratrol je detektovan u 17 od 18 analiziranih uzoraka vina sa prosečnom koncentracijama od 0,78 mg l-1 za crvena vina i 0,23 mg l-1 za bela vina. Najviša koncentracija trans-rezveratrola je nađena u uzorku crvenog vina Cabernet Sauvignon berbe 2002 godine. cis-Rezveratrol je detektovan u 12 od 18 analiziranih uzoraka vina sa prosečnom koncentracijom 0,55 mg l-1 za crvena vina, dok je u belim vinima od analiziranih 7 uzoraka detektovan samo u 2 uzorka sa koncentracijama 0,12 i 0,49 mg l-1. Visok sadržaj cis-rezveratrola u nekim uzorcima je verovatno posledica izomerizacije trans- u cis-rezveratrol tokom procesa proizvodnje vina.
