Chromatographic Studies on Triphala

Abstract

Chromatographic studies on Triphala, a well known ayurvedic
formulation, prepared from three constituents, viz., Haritaki, Beheda
and Amalaki, have been carried out with a view to standardize the
formulation. Thin layer chromatographic studies were carried out
using precoated silica gel fluorescent plates on the aqueous extracts
and ethyl acetate extracts of the three constituents and also Triphala
The choice of the solvent system toluene-ethyl acetate-formic acid
is discussed and its utility is demonstrated for complete resolution
of gallic acid from other components. Gallic acid therefore can be
used as a marker compound for standardizing Triphala
