Sesquiterpene lactones and other constituents from Tanacetum parthenium

Abstract

A reinvestigation of the aerial parts of Tanacetum parthenium afforded in addition to known compounds three pinene derivatives, two spiroketal enol ether polyines, four germacranolides; and six guaianolides, two of them being endoperoxides, and two secoguaianolides. The structures were elucidated by high field 1H NMR spectroscopy, mass spectroscopy and a few chemical transformations. The biogenetic relationships are discussed briefly. © 1982.
