Název v původním jazyce

Content of polyphenolic antioxidants and trans-resveratrol in the fruits of different varieties of vine (Vitis vinifera L.)

Popis výsledku v původním jazyce

Contents of polyphenolic antioxidants as total polyphenols and trans-resveratrol in grape musts, grape skins and seeds of twelve vine varieties from the harvests 2001 and 2002 were determined. Polyphenolic antioxidants of grape are very effective in preventing cancer and cardiovascular diseases. Total polyphenolic content was determined spectrophotometrically with phenol Folin-Ciocalteau´s reagent and trans-resveratrol content by HPLC method. The average annual total polyphenol contents in the years 2001 and 2002 were 171 mg/L and 324 mg/L in the must, 7 470 mg/L and 15 600 mg/kg DM in grape skins and 91 450 and 107 440 mg/kg DM in the seeds. The average annual trans-resveratrol values in the years 2001 and 2002 reached 0.817.10-2 mg/kg DM and 4.97.10-2 mg/kg DM in grape skins and 52.7.10-2 mg/kg DM and 4.63.10-2 mg/kg DM in the seeds and there was nearly no trans-resveratrol occurrence in the must. Obtained results were evaluated statistically by Statgraphic and Anova programmes. In t
