Abstract

The aerial parts of Kyrsteniopsis dibollii afforded, in addition to known sesquiterpene lactones, four new germacranolides and four guaianolides. Furthermore, two new pimarane derivatives and two unusual degraded pimaranes with an extra carbon atom were isolated. The structures are elucidated by high-field NMR spectroscopy.
