A new eudesmane derivative from Onopordon ambiguum.
Reinvestigation of Onopordon ambiguum extract afforded a new eudesmane derivative 1, in addition to the known elemanoid derivative 2. The structures of both compounds were determined by spectroscopic techniques, including 1H-, 13C-NMR, DEPT, 1H-1H and 1H-13C COSY analysis.
