Of 15 synthetic methyl glycyrrhetate glycosides, the monoglycosides having CH2OH-6 or Me-6 in their sugar moieties and the diglycosides having a (1-->4) linkage between the sugar residues showed higher haemolytic activities than the others. The beta-maltoside and beta-lactoside exhibited much stronger antifungal activities against Trichophyton mentagrophytes than the others. However, none of them exhibited antibacterial activity against Staphylococcus aureus or Bacillus subtilis.
