Sažetak
Concentrations of free resveratrol monomers (resveratrol) in red wines from region of Dalmatia (Croatia) were determined using a direct injection isocratic UV-HPLC method. The amount of resveratrol, calculated as sum of free cis- and trans-resveratrol monomers, ranged from 0.5 to 8.6 mg/L of red wine, mean 2, 98 mg/L. No significant correlation was confirmed between resveratrol content and concentration of total phenols, total flavonoids or total anthocyanins. The grape variety influenced resveratrol contents in red wines. The highest levels of resveratrol were found in Merlot, followed by Plavac, Babić, Lasin, Vranac, and Plavina. The lowes levels were found in Cabernet sauvignon and Trnjak. According to the obtained results red wines from the region of Dalmatia (Croatia), especially some wines produced from Merlot and Plavac mali cv., can be a good dietary source of resveratrol.
