    Red wine as resveratro protectiv system

  • Original language description

    The study describes an isomerization of trans -resveratrol exposed to diffused daylight in dependence on temperature and character of liquid sample (type of solvent, wine #).These effects were investigated using the reverse-phase-HPLC method. Trans -resveratrol isoform was light sensitive and under daylight isomerized to cis-form very easily. The exposition of trans -resveratrol solution by higher temperatures did not induce isomerization reaction if that was kept in dark. The wines were analyzed immediately after opening (0 hour), and again after 48 hours and after 17 days. The concentration of resveratrol in tested red wines was stable at 4 °C, under room temperature the total amount of resveratrol in all cases increased.

    Červené víno jako protektivní systém resveratrolu

  • Czech description

    Práce popisuje průběh izomerace trans-resveratrolu na denním rozptýleném světle v závislosti na teplotě a také charakteru vzorku (typ rozpouštědla, víno ...). Tento efent byl zkoumán pomocí HPLC s elektrochemickou detekcí. Trans-resveratol je velice citlivý na světlo a snadno přechází na cis-formu. Je-li roztok trans-resveratrolu umístěn v temnu, nedochází k izomeraci ani za zvýšené teploty. Vína byla analyzována ihned po otevření , po 48 h a 17 dnech. Koncentrace resveratrolu byla v červených vínech stabilní při 4°C, při pokojové teplotě došlo ke zvýšení obsahu resveratrolu.
