Oxidative stress plays a key role in the pathophysiology of AD, and it has been suggested that antioxidants may slow the progress of the disease. In this study, the possible protective effects of pelargonidin (a natural flavonoid) against amyloid β (Aβ)-induced behavioral deficits was investigated in rats. Methods: Adult Wistar male rats were treated with intrahippocampal injections of the Aβ (aa 25-35) and intraperitoneal injection of pelargonidin. Learning and spatial memory were tested using the Morris water maze (MWM) task. The antioxidant activity was evaluated using the ferric reducing/antioxidant power assay (FRAP assay). Data were analyzed using SPSS 20, and value of p≤0.05 was considered significant. Results: The results of this study showed that Aβ significantly increased escape latency and the distance traveled in the MWM, and pelargonidin attenuated these behavioral changes. Aβ induced a significant decrease in the total thiol content of hippocampus, and pelargonidin restored the hippocampal antioxidant capacity. Conclusion: The results of this study suggest that pelargonidin can improve Aβ-induced behavioral changes in rats.
