Glycyrrhizic Acid — impurities and related standards

All 3 Glycyrrhizic Acid-related compounds in the CATO catalogue, listed with their CAS numbers, molecular formulae and stock status. If the compound you need is not listed, send the structure or the impurity designation and we will check whether it can be synthesised or isolated.

Glycyrrhizic acid is a triterpenoid saponin obtained from liquorice root and used as a pharmaceutical and food ingredient, with the related aglycone glycyrrhetinic acid also appearing in medicinal products. Its impurity profile follows from the glycosidic structure and from extraction: hydrolytic cleavage of the sugar chain, oxidation and rearrangement products of the triterpene core, and related saponins co-extracted from the plant material all require examination. The glycyrrhizic acid standards collected here are non-compendial impurities, provided as individual characterised lots with defined identities. They are intended for peak identification, purity assessment of the bulk material, and the development of chromatographic methods capable of separating closely related triterpenoid saponins.
