Abstract

The aerial parts of Calea pinnatifida contain a 4-glycosyloxybenzoic acid, anisic acid, tetradeca-4E,6E,12E-trien-8,10-diyn-1-ol and arucanolide. The structural elucidation of this germacranolide included comparison with neurolenin B whose stereochemistry had been defined by X-ray crystallographic analysis. The data suggest that the structures of all other known germacranolides of the genus Calea should be revised.
