A bicyclic sesquiterpene dialdehyde “Polygodial” has been isolated from leaves of the New Zealand tree Pseudowintera colorata and shown to possess strong antibiotic activity against the yeast Candida albicans. Polygodial was also found in Drimys winteri but was absent from P. axillaris and P. traversii.
