✦ Synopsis

Detailed analysis of the 'H and 13C NMR spectra of three natural quinone-methide triterpenoids, pristimerin, tingenone and 20-hydroxytingenone, was carried out by the application of two-dimensional H-'H and ' H-13C shift correlation techniques. Some previous 'H and "C assignments have been revised. KEYWORDS 'H NMR l3C NMR Quinone-methide triterpenoids Revised assignments

## 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
