This study was designed to investigate the protective effects of Sasa borealis leaves on high glucose-induced oxidative stress in human umbilical vein endothelial cells (HUVECs). Freeze-dried Sasa borealis leaves were extracted with 70% methanol and followed by a sequential fractionation with dicholoromethan, ethyl acetate, butanol and water. The ethyl acetate fraction from Sasa borealis leaves extract (ESLE) was used in this study because it possessed the strongest antioxidant activity among the various solvent fractions. Exposure of HUVECs to 30 mM high glucose for 48 hr resulted in a significant (p<0.05) decrease in cell viability, glutathion (GSH) concentration, activities of antioxidant enzymes including superoxide dimutase (SOD), glutathion peroxidase (GSH-px) and catalase, and a significant (p<0.05) increase in intracellular ROS and lipid peroxidation formation in comparison to the cells treated with 5.5 mM glucose. ESLE treatment decreased intracellular ROS and lipid peroxidation formation and increased cell viability, GSH concentration and expressions of SOD and catalase in HUVECs. These results suggest that ESLE may be able to protect HUVECs from high glucose-induced oxidative stress, partially through the antioxidative defense systems.
