Abstract

Eight new guaipyridine sesquiterpene alkaloids, rupestines F—M (1—8) were isolated from the leaves of Artemisia rupestris and their structures were elucidated on the basis of 2D-NMR data. The absolute configurations of 1—8 have been assigned by comparison of their experimental and calculated circular dichroism (CD) spectra.
