Increased oxidative stress is widely accepted to be a factor in the development and progression of Alzheimer's disease (AD). Here we introduced Salvia sahendica as a protective agent in differentiated PC12 cells, which are commonly considered to be a reliable model of neuronal cells. Our results demonstrated that S. sahendica has antioxidant and antiglycating properties in in vitro system and these properties are expanded into H(2)O(2)-induced model. S. sahendica inhibited H(2)O(2)-induced cell death in PC12 cells. We further showed that this plant exerts its protective effect by increasing superoxide dismutase and catalase levels, reducing lipid peroxidation and upregulating hemoxygenase-1 and glutamylcysteine synthetase proteins. This study raises the possibility of developing S. sahendica as a potential neuroprotective agent.
