Key words: «one-pot», subcritical water, glycyrrhetinic acid, roots of licorice Glycyrrhiza glabra L.

For the first time starting from the roots of licorice Glycyrrhiza glabra L. the
glycyrrhetinic acid (GLA) was obtained in a good yield using an «one-pot» method in
medium of subcritical water (SBW) that serves as a reactant and a solvent. This method
of preparation of GLA allows one to avoid the use of toxic organic solvents and does
not require the separate stages of extraction and hydrolysis. The good yields of the
targeted GLA can be obtained for the period, which is ten times shorter than needed
by the traditional procedures. The proposed method is promising for the future
development of low-cost and environment friendly technologies for GLA producing
in pharmaceutical, food and cosmetic industries.
