Detailed analysis of the 1 H and 13 C NMR spectra of three natural quinone‐methide triterpenoids, pristimerin, tingenone and 20‐hydroxytingenone, was carried out by the application of two‐dimensional 1 H 1 H and 1 H 13 C shift correlation techniques. Some previous 1 H and 13 C assignments have been revised.
