Abstract
Red wine polyphenol extracts (RWPE) have been shown to increase nitric oxide (NO) release from EA.hy926 endothelial cells [1]. Trans-resveratrol seems to partly contribute to this effect by inducing endothelial NO-synthase (eNOS) expression [1]. Aim of this study is to identify further major active component(s) by bio-assay guided fractionation.
