Of special interest in this respect are the major triterpenoids contained in the root extract obtained from plants of the common licorice (Glycyrrhiza glabra L.) and Ural licorice (Glycyrrhiza uralensis Fisher ) species. These substances are represented by 18 -glycyrrhetic acid (I) and its modified analogs, which serve as the base for effective antiinflammatory, antiallergic, and antiulcer preparations [2, 5 – 9]. The antiulcer drugs include the sodium salt of acid I (glycyrrhenate sodium) [2] and the disodium salt of acid I succinate (carbenoxolone, II) %U https://repo.bashgmu.ru/publication/625
