Rupestines F-M, new guaipyridine sesquiterpene alkaloids from Artemisia rupestris

Chem Pharm Bull (Tokyo). 2012;60(2):213-8. doi: 10.1248/cpb.60.213.

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.
