Effect of G. tinctoria extract on oxidative stress induced by high d-glucose and hydrogen peroxide. Reactive Oxygen Species (ROS) levels were determined by 2′,7′-dichlorofluorescein fluorescent probe in HUVECs incubated with M199 and 25 mM d-glucose (HD) or M199 and 100 μM H2O2 in absence or presence of 200 μg/L of G. tinctoria extract (labeled as HG + G. tinctoria or H2O2+G. tinctoria, respectively). Changes in ROS levels are shown as rate of control. Values are mean ± SEM, n = 3. *p < 0.05 versus vehicle, Фp < 0.05 versus high d-glucose; γp < 0.05 versus H2O2
