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.
