title: 1H and 13C NMR spectral assignments of four dammarane triterpenoids from carnauba wax.
abstract: The phytochemical investigation of carnauba wax led to the isolation of three new dammarane triterpenoids 1, 2 and 4, together with the known triterpene 3. The structures of the new compounds were determined by 1D and 2D NMR spectroscopy and by comparison with published data for closely related compounds.
