Pharmacognostical and phytochemical evaluation of Vara Asanadi Kwatha

Abstract

Vara Asanadi Kwatha (VAK) is a compound Ayurvedic formulation prescribed in the management of obesity. Pharmacognostical study counting both macroscopic and powder microscopy of raw drug exposed the quality and genuineness of all the constituents of VAK. Organoleptic features of coarse powder made out of the crude drugs were within the standard range. Specific gravity of the decoction was 1.0185 and pH was 5.5.Total solid content present in the Kwatha was 4.525% w/v, total ash 0.949% w/v, and acid insoluble ash was 0.052% w/v. Iron assay showed the presence of Fe ₂ O ₃ as 0.065% w/v. Qualitative scrutiny demonstrated the presence of flavonoids and tannis. Thin Layer Chromatography (TLC) and High Performance Thin Layer Chromatography (HPTLC) were carried out after organizing appropriate solvent system in which maximum three spots were distinguished in TLC and nine spots in HPTLC and most of the R _f values were identical when done with different sample extractive methods. This shows the presence of certain definite constituents in the decoction and is helpful for the easy separation of these constituents.
