A Further Contribution to the Triterpenoid Constituents of Glycyrrhiza glabra L

Abstract Pentacyclic Triterpenoids, G lycyrrhiza glabra, 1H and 13C Chemical Shifts Five pentacyclic triterpenoids have been isolated from the minor constituents of local liquorice roots, one of them (8) has not been isolated before from liquorice root. Their struc­ tural formulae and stereochemical configuration was determined by spectroscopic methods. 13C and 1H NMR data have been compiled.
