Abstract
In the present study, two brands of Kumaryasava and Mustakarista medicinally important ayurvedic preparations were studied for quality control parameters like physiochemical properties, ethanol content by specific gravity and gas chromatographic methods and the total phenolic content. Evaluation of physiochemical properties and total phenolic contents resulted in establishing ranges for routine analysis. In both the formulations, ethanol content observed by specific gravity method varied from 0.9 to 1.9% on day 0 and reduced on storage for 30 days ranging from 0.1-0.6% v/v. Similarly, ethanol content determined by GC on day 0 varied from 0.1-1.6% v/v and on 30th day from 0.011-0.025% v/v. This reduction in ethanol content on storage might be due to loss caused by frequent opening of the container.
