Abstract Crushed fruits and herbal parts of Cymbocarpum wiedemannii, endemic in Turkey, were separately subjected to hydrodistillation. The oils were analyzed by GC/MS. Fifty-six compounds representing 96% of the oil were identified in the fruit oil whereas 33 compounds making up of 94% of the oil were characterized in the oil obtained from aerial parts. (E)-2-decenal (39.3% and 31.7%), (E)-2-dodecenal (16% and 11.4%), (E)-2-tetradecenal (8.8% and 4.1%), and 2-decenoic acid (4.5% and 19-9%), decanoic acid (2% and 8.7%) and 2-dodecenoic acid (1.6% and 6.6%) were main constituents in the fruit and herb oils, respectively.
