Effect of Withania Somnifera (L.) root extract\'s on PC12 induced by hydrogen peroxide, study

Abstract

The L. is also used as a crude medicament that mostly effected in various neurological and immunological disorders. It is also known as Ashwagandha and “Indian ginseng” in Indian region. There is a lack of information on the possible neuroprotective properties of W. somnifera root against HO- and Ab(1-42)-induced cytotoxicity, which are now targeted for innovative treatments for dementia, particularly dementia of the Alzheimer's type (AD). According to this research, we prepared an aqueous extract of dried roots of W. somnifera that possess the protective effect against Ab- aggregated fibril and HO cytotoxicity through MTT assay with the help of differentiated rat pheochromocytoma PC12 cell. The findings indicate that, in a concentration-dependent manner, pretreatment of differentiated PC12 cells with aqueous extracts of W. somnifera root strongly protects differentiated PC12 cells against both H2O2- and Ab(1-42)-induced cytotoxicity. The W. somnifera extract was examined using liquid chromatography-serial mass spectrometry in order to look into the substances that could be responsible for the effects that were seen. Withanolide derivatives, notably withaferin A, were found in abundance. These findings support the hypothesis that W. somnifera may be used ethnopharmacologically to treat oxidative stress-related cognitive and other neurodegenerative illnesses. They also show the neuroprotective activities of an aqueous extract of W. somnifera root.
