Abstract
An ethnopharmacological review reveals that Kushmanda ghrita is a polyherbal formulation made from Glycyrrhiza glabra L. (Yashtimadhu) and Benincasa hispida (Thunb.) Cogn. (Kushmanda) in ghrita (cow's ghee) and serves as a carrier for its active compounds. Yashtimadhu and Kushmanda have been reported to exhibit memory-enhancing and antioxidant activity.
Aim of the study
This study aimed to standardize Kushmanda ghrita and evaluate its neuroprotective activity against trimethyltin-induced dementia in albino Wistar rats.
Materials and methods
Kushmanda ghrita was standardized for various parameters according to the AYUSH protocol. The HPTLC method was developed and validated to standardize Kushmanda ghrita for the markers rutin, glycyrrhizin, gallic acid, and quercetin. Well-established parameters, such as locomotor activity, behavioral parameters (Morris water maze, elevated plus maze, social recognition test, and novel object recognition test), biochemical parameters (malonaldehyde, glutathione, and catalase), and histopathological studies were performed to evaluate the neuroprotective effects of trimethyltin-induced dementia in rats.
Results and discussion
In addition to its organoleptic properties, Kushmanda ghrita was standardized for its specific gravity, viscosity, refractive index, loss on drying, pH, rancidity, iodine value, saponification value, acid value, peroxide value, heavy metal test (As, Cd, Hg, and Pb), microbial contamination test, and specific pathogen tests. A novel HPTLC method was developed to simultaneously detect and quantify selected markers (ICH Q2 R2 guidelines). Kushmanda ghrita treated groups significantly improved cognition and memory trimethyltin-induced dementia in rats. It also reduces malondialdehyde, glutathione, and catalase levels, thereby reducing oxidative stress in the brain. In addition, a brain histopathology study revealed less damage to neuronal structures in Kushmanda ghrita-treated animals than in diseased animals.
Conclusion
Kushmanda ghrita was standardized, and an accurate, precise, robust, and specific HPTLC analytical method was established. Based on the pharmacological activity data, the study concludes that Kushmanda ghrita effectively reduces oxidative stress and prevents damage to hippocampal neurons, probably due to learning and memory enhancement activity.
期刊介绍:
The Journal of Ethnopharmacology is dedicated to the exchange of information and understandings about people''s use of plants, fungi, animals, microorganisms and minerals and their biological and pharmacological effects based on the principles established through international conventions. Early people confronted with illness and disease, discovered a wealth of useful therapeutic agents in the plant and animal kingdoms. The empirical knowledge of these medicinal substances and their toxic potential was passed on by oral tradition and sometimes recorded in herbals and other texts on materia medica. Many valuable drugs of today (e.g., atropine, ephedrine, tubocurarine, digoxin, reserpine) came into use through the study of indigenous remedies. Chemists continue to use plant-derived drugs (e.g., morphine, taxol, physostigmine, quinidine, emetine) as prototypes in their attempts to develop more effective and less toxic medicinals.
