Název v původním jazyce

The contents of total polyphenolic compounds and trans-reveratrol in white Riesling originated in the Czech Republic

Popis výsledku v původním jazyce

Wine is a significant source of antioxidants in human nutrition. Every glass of wine contains approximately 200 different phenolic compounds, of which several have been noted as antioxidants because they have been shown to slow the potentially damaging cell oxidation process. In white Riesling from different wine-growing sub-regions, kinds of wine, years of harvest and vintners the content of total polyphenols (TP) was determined using spectrophotometric method and the content of trans - resveratrol (R)by the HPLC method. The TP content was presented as gallic acid equivalent per litre of wine and the content of R as trans-resveratrol per litre of wine. TP values in wine-growing region of Bohemia ranged from 223.0 to 532.7 mg/l (average content 330.3mg/l), in wine-growing region of Moravia from 175.0 to 465.0 mg/l (average content 271.7 mg/l) and R values in the wine-growing region of Bohemia ranged from <0.033 to 0.421 mg/l (average content 0.117 mg/l), in wine-growing region of Mor
