Protection of PC12 cells from hydrogen peroxide-induced cytotoxicity by salvianolic acid B, a new compound isolated from Radix Salviae miltiorrhizae

A number of studies indicate that reactive oxygen species (ROS) are involved in neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD). The neuroprotective effects of salvianolic acid B (SalB) from Radix Salviae miltiorrhizae (RSM) against hydrogen peroxide (H2O2)-induced rat pheochromocytoma line PC12 injury were evaluated in the present study. Vitamin E, a potent antioxidant, was employed as a positive...
