Abstract

Ferulago angulata is a medicinal herb from the Apiaceae family known for its antioxidant, anti-apoptotic, and neuroprotective properties. This study aimed to assess the effects of F. angulata extract on neurobehavioral and biochemical parameters in scopolamine-induced amnesic rats. Fifty-six male Wistar rats were divided into seven groups and orally treated with F. angulata extract (100, 200, 400 mg/kg) and Rivastigmine (1.5 mg/kg) for 10 days. Starting on the sixth day of treatment, the Morris water maze behavioral study was conducted to evaluate cognitive function, with scopolamine administered 30 min before training. Biochemical assays, including monoamine oxidase and oxidative stress measures, were performed on hippocampal tissue. Results showed that extract treatment significantly attenuated scopolamine-induced memory impairment in a dose-dependent manner. Following scopolamine administration, malondialdehyde levels and monoamine oxidase A/B activity increased, while total thiol content and catalase activity decreased compared to the control group. Pretreatment with F. angulata extracts ameliorated the scopolamine-induced impairment in all factors. Toxicological evaluation of liver, lung, heart, and kidney tissues did not indicate any side effects at high doses. The total extract of F. angulata prevents scopolamine-induced learning and memory impairment through antioxidant mechanisms and inhibition of monoamine oxidase. These results suggest that F. angulata extract is effective in the scopolamine model and could be a promising agent for preventing dementia, especially Alzheimer’s disease. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
