New Eudesmanolides Related to Torrentin from Artemisia herba-alba subsp. valentina.

1991

The reinvestigation of aerial parts of A. herba- alba subsp. valentina afforded four new eudesmanolides, all of them closely related to torrentin. Their structures were deduced by spectroscopic and chemical methods

13C NMR spectra of eudesmanolides I—eudesman-12,6-olides

1987

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