The authors isolated from the aerial parts of Ursinia anthemoides (L.) POIRET another five sesquiterpenic lactones, IV, V, VII, IX and X and have derived for them their structures and configurations mainly on the basis of 1H NMR spectroscopy and CD measurements; for compounds IV and V absolute configurations have also been proposed.
