"Contents of polyphenolic antioxidants as total polyphenols (TP), free trans-resveratrol (R) and their antiradical activity (ARA) in grape skins and seeds of vine varieties and TP in grape musts originated from 5 wine-growing Czech areas from the harvest 2003 were determined. Polyphenolic antioxidants of grape are very effective in preventing cancer and cardiovascular diseases. TP content was determined spectrophotometrically with phenol Folin-Ciocalteau\u00B4s reagent, R content by HPLC method, and ARA employing the 1,1-diphenyl-2-picrylhydrazyl stable free radical (DPPH\u00D7). Obtained results were evaluated statistically by Statistica programme. TP did not show statistically significant differences among analysed varieties (p < 0.05) in grape seeds and skins, but regarding wine-growing regions a significant difference in TP (p < 0.10) in grape skins was found. ARA (p<0.05) was not significant both, for grape seeds as well as grape skins in relation to wine-growing regions and varieties. The highest TP conte"@cs . .
