Sesquiterpene lactones from Carpesium abrotanoides.[Pubmed: 18948175]

METHODS AND RESULTS:
Phytochemical study on the ethanol extract of the aerial parts of Carpesium abrotanoides led to the isolation of two new sesquiterpene lactones, carabrolactone A (1) and Carabrolactone B (2). Their structures were elucidated on the basis of extensive spectroscopic analysis.
