Effect of grewia hirsuta vahl ethanolic root extract on cognition in scopolamine induced amnesia

Abstract

Objective Alzheimer's illnesses are becoming medical nightmares because there is no exact solution and existing nootropic medicines (Piracetam, tacrine, and metrifonate) have significant drawbacks. The goal of this study was to see if the ethanolic root extract of Grewia hirsuta (ERGH) could improve memory in rats who had been given scopolamine.
 Materials and procedures At rats, ERGH was given orally in dosages of 200 and 400 mg/kg for 28 days, followed by Scopolamine (18 mg/kg i.p.) from the 25th to the 27th day. The usual nootropic drug was piracetam (200 mg/kg). The elevated plus maze (EPM), Morris water maze (MWM), and passive avoidance (PA) paradigms are used to assess cognitive functioning. Invivo anti-oxidant activity and brain acetylcholine esterase (AchE) activity were assessed.
 Results: At the indicated doses, ERGH extract showed a substantial memory-enhancing activity by decreasing the transfer latency in EPM, increasing the escape latency in MWM, and increasing the shock-free zone in PA. In scopolamine-induced amnesia rats, pretreatment with ERGH resulted in a significant drop in AchE enzyme, an increase in enzymatic antioxidant, and a decrease in MDA levels.
 Conclusion Because of its several favorable benefits, such as memory-improving properties, anticholinesterase activity, and antioxidant activity, ERGH may prove to be a useful drug in the current study, and it would be important to investigate its potential in the care of Alzheimer's patients.
