Abstract: The study aims to analyse the physicochemical and phytochemical characteristics of Yashtimadhu (Glycyrrhiza glabra) in aqueous and ethanolic extracts and determine the ash value and extractive value of the drug. Using Soxhlet equipment, the extract was prepared from powdered Yashtimadhu drugs for 20 hours using water and ethanol as solvents. The analysis of physicochemical properties of Yashtimadhu extracts includes ash value and extractive value etc. The study of phytochemical screening of Yashtimadhu includes tests for carbohydrates, saponins, flavonoids, alkaloids, etc. The percentage yield of ethanol extract is found to be 9.73%. The physicochemical parameters of the aqueous solution and ethanol were analysed and found within limits. The ethanolic extract of Yashtimadhu showed the presence of alkaloids, flavonoids, tannins, phenols, saponins, carbohydrates, glycosides and phytosterol. The amounts of total flavonoids, phenol and ascorbic acid were 185.14 mg, 481.47 mg per 1 gm, and 33.81 µg/ml of aqueous extract 218.92 mg, 507.62 mg per 1 gm, and 42.38 µg/ml of the ethanol extract, respectively. It was found that the phytochemical constituents are very much enriched in the Yashtimadhu (Glycyrrhiza glabra) extract and can be used for the development of new formulations.
