ResumoThe investigation of nine Eriocephalus species afforded in addition to known compounds 40 new ones: 10 guaianolides, eight eudesmanolides, a germacranolide, a sesquiterpene lactone with new carbon skeleton, 18 derivatives of costic acid, a seco-eudesmane diketone and a chrysanthemol derivative. The structures were elucidated by high field NMR spectroscopy and a few chemical transformations. The chemotaxonomy of the genus is discussed briefly.
