Abstract
From the bark of Drimys winterii Forst., the drimane derivatives drimendiol, polygodial, isotadeonal and isodrimeninol were isolated. Complete and unambiguous ^1^H and ^13^C NMR chemical shift assignments of these compounds were achieved by COSY experiments, ^13^C/^1^H 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.
