Sesquiterpene lactones from Picris pauciflora Willd.

Wanda Kisiel

Abstract


The aerial parts of Picris pauciflora Willd. (Asteraceae) yielded 11β, 13-dihydrolactucin, while the roots of the plant afforded 3-β-D-glucopyranosides of 11β, 13-dihydrozaluzanin C and 9α-hydroxy-11β, 13-dihydrozaluzanin C (ixerin F). The guaianolides were isolated from ethanol extracts using chromatographic methods and were identified on the basis of spectral analysis. They are reported for the first time from this species.
