    Author: Xiang L, Xiao L, Wang Y, Li H, Huang Z, He X.
    Journal: Food Chem; 2014 Aug 01; 156():258-63. PubMed ID: 24629966.
    Abstract:
    Moderate consumption of red wine reduces the risk of heart disease and extends lifespan, which these healthy benefits are often attributed to its high antioxidant content. The relative contributions of wine polyphenols in healthy benefits were studied in this study. Among all wine polyphenols, caffeic acid was the richest one, while gallic acid showed the highest free radical scavenging activity. There was no significant difference between the prime red wine and the red wine adding 10-fold resveratrol on neuroprotective effects on SH-SY5Y cell line. The contribution percentage of resveratrol to the antioxidant activity of red wine was less than other tested polyphenols. It suggested that resveratrol may be negligible with respect to healthy benefits of red wine.
