Five pentacyclic triterpenoids have been isolated from the minor constituents of local liquorice roots, one of them has not been isolated before from liquorice root. Their structural formulae and stereochemical configuration was determined by spectroscopic methods. 13C and 1H NMR data have been compiled.
