Abstract

From the bark of Drimys winterii Forst., the drimane derivatives drimendiol, polygodial, isotadeonal and isodrimeninol were isolated. Complete and unambiguous 1H and 13C NMR chemical shift assignments of these compounds were achieved by COSY experiments, 13C/1H shift correlation diagrams and NOE experiments. Isotadeonal and isodrimeninol were found for the first time in this plant species. Copyright © 2004 John Wiley & Sons, Ltd.
