An improved technique for the estimation of glycyrrhizic acid has been developed in Glycyrrhiza glabra L. The technique is based on the estimation of glycyrrhizic acid through its aglycone, the glycyrrhetic acid. The procedure reported so far give erroneous results because of the fact that the amount of non-glycyrrhizic acid components accompanying glycyrrhizicacid were not taken into consideration during the processing of samples. 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.
