Olive leaf extract (OLE) can be obtained as biowaste and is extensively used a food
supplement and an over-the-counter drug for its beneficial effects. New studies have
investigated OLE concerning the role of oxidative stress in the pathogenesis of vascular
disease. This in vitro study aims to evaluate if OLE extracted from the Tuscan Olea europaea
protects endothelial cells against oxidative stress generated by reactive oxygen species
(ROS). Methods: OLE total polyphenols (TPs) were characterized by the Folin–Ciocalteu …

Background. Olea europaea is one of the most ancient trees of the Mediterranean region.
Olive leaf extracts (OLE) have aroused interest in researchers from different scientific
disciplines mainly due to the distinctive phenolic composition allegedly related to potent
biological activities. Objectives. The aim of the present s study was to evaluate: A) the
properties of OLE extracted from the Tuscan Olea europaea to protect endothelial cells
against oxidative stress generated by reactive oxygen species (ROS) in 2D culture and …
