- Abstract
- In this study, the protective effects of 17 Korean native plants against amyloid beta peptide (A beta)-induced oxidative stress were screened using the 2',7'-dichlorofluorescin diacetate assay and the 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay. Ipomoea batatas exerted the highest protective effects against oxidative stress and was selected for further investigation. To confirm the protective activity of this extract, the I. batatas extract was fed to ICR mice that had been injected with A beta to induce neuronal deficits. In these experiments, the extract of I. batatas significantly reversed A beta-induced neurotoxicity as assessed by the passive avoidance test, a behavioral experiment. Moreover, I. batatas administration reduced the level of lipid peroxidation and increased catalase activities in biochemical studies using the brain tissue of mice. These results indicate that I. batatas might be beneficial against Alzheimer's disease, especially by limiting oxidative stress in the brain.
