Triterpenoid Saponins from the Roots of Glycyrrhiza Glabra

Abstract

Seven new oleanane-type triterpenoid saponins (glabasaponin A-G) were isolated from the roots of Glycyrrhiza glabra together with a known compound macedonoside A. The structures of compounds 1-7 were determined on the basis of 1D and 2D NMR as well as the MS data analyses. The sugar moieties of compound 5 were confirmed by gas chromatography after hydrolysis.
