Abstract
Extraction of the aerial parts of Chrysolaena verbascifolia afforded a number of new piptocarphols (hirsutinolides), two new cadinanolides, two rare lignans and several common plant constituents, while the aeri al parts of Lessingianthus rubricaulis furnished a new cadinanolide, v omifoliol and several triterpenes. Structures were established by high resolution NMR spectrometry. The possibility that the isolated sesqui terpene lactones are artefacts formed during the isolation process is discussed.
