Summary

A spectrophotometric method for determining glycyrrhizic acid in a thick licorice extract, dry licorice powder, and licorice roots after its chromatographic separation from the accompanying substances in a thin layer of sorbent has been proposed. The limit of detection of glycyrrhizic acid is 8 µg/ml. The concentration of glycyrrhizic acid in the thick extracts is ∼15.49%, in the dry powder ∼12%, and in licorice roots ∼4.3%.
