Pharmaceutical and Analytical Study of Vasa Arka

Abstract

Vasa (Adhatoda vasica Nees) is used in multiple Ayurvedic formulations. One such formulation is Vasa Arka which is said to be beneficial for treating conditions like Jwara, Chardhi, Kushta, Meha and Kshaya. Presently, Arka is gaining importance due to its sterility and shelf life. The present study focuses on the preparation and analysis of Vasa Arka. Materials and method: Fresh leaves of Vasa were collected and were authenticated from experts. To the measured quantity leaves 1/20^th part of water (v/v) was added Arka was extracted in distillation apparatus. The prepared Arka was tested for its quality with help of Physico-chemical parameters and GCMS (Gas Chromatography Mass Spectrometry). Results and discussion: The percentage yield of Vasa Arka was 27.51%. The pH was 3.50, indicating acidic nature. Specific gravity (1) and viscosity (0.001kgcm⁻¹s⁻¹) were comparable to water, while the refractive index (1.346) suggested the presence of dissolved constituents. GC-MS analysis revealed alcohols, ketones, esters, phenols, and halogenated compounds. Conclusion: The preparation of Vasa Arka was pharmaceutically feasible; however, the yield was low. The quality control parameters established through this work can be considered as preliminary standards for Vasa Arka.
