Standardization of Selected Asavas and Arishtas

Abstract

In the present investigation and standardization of selected asavas
and arishtas have been done by preliminary phytochemical,
chromatographic and analytical studies. The preliminary phytochemical
study revealed the presence of phenolic compounds in all
the selected asavas and arishtas and no flavanoids have been detected.
Out of the nine solvent systems used for the chromatographic
study, only the solvent n-butanol : glacial acetic acid: water system
showed a good separation of asavas and  arishtas and in other solvent
systems streaking was observed.  Aravindasava,asokarista,
dasamularista and kumaryasava gave positive results for Borntrager
reaction. Analytical study revealed the lowest pH . 3.42 in
kumaryasava and highest pH 4.8 in amritarista; specific gravity
ranges in betwecn 1.0177 (aravindasava) and 1.2612
(dasamularista) and lowest alcohol content was observed in
amritarista (3.6%) and highest in asokarista (10.5%).
