摘要：

The aerial parts of Cronquistia pringlei afforded, in addition to some known germacranolides and guaianolides, four new guainolides a lactone with a new carbon skeleton, i.e. a heliangolide with a cyclopropane ring. The structures were elucidated by high field NMR techniques. The chemotaxonomy is discussed briefly.
