title: The effect of artichoke (Cynara scolymus L.) extract on ROS generation in HUVEC cells.
abstract: The effect of an artichoke extract on induced reactive oxygen species (ROS) generation in cultured human umbilical endothelial cells (HUVECs) and its reductive properties were evaluated. Preincubation of HUVEC cells with the artichoke extract at concentrations of 25-100 microg/mL for 24 h abolished ROS generation induced by LPS and oxyLDL as evaluated by the fluorescence intensity of 2',7'-dichlorofluorescein (DCF). Potent, concentration-dependent reductive properties of the artichoke extract were demonstrated by the reduction kinetics of cytochrome c in reference to ascorbate were also revealed. The results of the present study the warrant application of artichoke extracts as endothelium protecting agents.
