Complete 1 H and 13 C NMR chemical shift assignments were made for taraxerene from HMQC and HMBC spectra. Methyl proton shifts were assigned for 11 other taraxerenes. Molecular mechanics calculations and NMR evidence supported the p ‐bromobenzyl acetylaleuritolate x‐ray conformation for taraxerenes in solution. © 1998 John Wiley & Sons, Ltd.
