## Abstract The ^13^C NMR spectral data of 18 eudesmane derivatives, mainly acids and esters of natural and synthetic origin, are reported, and the γ‐effect of the epoxide ring in two diastereoisomeric epoxy esters is discussed.
The 13C NMR spectra of 26 eudesmanolides of natural and synthetic origin have been measured, including the naturally occurring sesquiterpene lactones artemisin, torrentin, rothin-A and rothin-B and several semi-synthetic eudesman-12,dolides obtained from artemisin. The chemical shift values of the d
