The 13CNMRspectra 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‐12,6‐olides obtained from artemisin. The chemical shift values of the different compounds are compared and the effects of the substituents are discussed.
