Monitoring trans-Resveratrol in Grape Berry Skins During Ripening and in Corresponding Wines by HPLC

Year: 2015
Type: article
Abstract: T rans-resveratrol (3,5,4'-trihydroxy-trans-stilbene) is naturally present in the skin of grapes and therefore is expected to occur in grape products.Recently, there has been a renewal of interest in wine as medical treatment for various disorders.In this study, berry skins of fi ve red grape varieties were analysed at weekly intervals for trans-resveratrol production, during 2012 and 2013 harvest.The obtained wines were also evaluated.Quantification of trans-resveratrol in grape skin extracts and wines was carried out by high-performance liquid chromatography.Favourable viticultural climate during harvest in 2012 resulted in a higher content of trans-resveratrol.The highest trans-resveratrol content was in Pinot Noir and Feteasca Neagra grape varieties, both in berry skins and wines, while the lowest amounts were identifi ed in Cabernet Sauvignon variety.We can conclude that there was a signifi cant correlation between the content of trans-resveratrol in grape skins and that in the respective wine.
