Standardisation of ayurvedic medicines-dasamulam kasayam.

In a project on the analysis and standardization of Ayurvedic medicines, a chemical methodology for Dasamulam Kasayam for the comparison of market samples with a laboratory sample of Dasamulam Kasayam, and recording of characteristics like colour, consistency, smell, taste acidity, density, water soluble content and ash content. Adsorption of the Kasayam on silicagel, followed by extraction with selected solvents (petroleum ether, CHCL3, EtOAc and EtOH) as well as TLC pattern of each extract, together with the TLC pattern of total crude aglycones formed by the acid hydrolysis of the ethanol extract are experimentally determined. Market samples are compared with the reference sample using the same physical and chemical characteristics.
