An Improved Method of Analysis of Glycyrrhizic Acid in Mulethi (Glycyrrhiza glabra L.)

Abstract

An improved technique for the estimation ofglycyrrhizic acid has been developed in Glycyrrhiza glabra L. The technique
is based on the estimation ofglycyrrhizic acid through its aglycone, the glycyrrhetic acid. The procedure reported so far give
erroneous results because ofthe fact that the amount of non-glycyrrhizic acid components accompanying glycyrrhizic acid
were not taken into consideration during the processing ofsamples. This method is considered to be more accurate as it also
estimates the glycyrrhizic acid present during the preliminary processing of samples i.e. filtration and washings etc.
