VOLATILES FROM ZOSTERA-MARINA

The essential oil from the shoots of the marine embryophyte, Zostera m al ina was prepared by simultaneous distillation-extraction. Volatile compounds in the oil were identified by GC and GC-mass spectrometry. T he major constituents were phytol, hexadecanamide, octadecanamide, pen tadecane, heptadecane, nonadecane, (8Z, 11Z)-heptadecadienal (HDD), (8 Z)-heptadecenal (HD), (9Z, 12Z, 15Z)-octadecatrienal and (9Z, 12Z)-oct adecadienal, HDD and HD were shown to be formed enzymatically from lin oleic acid and oleic acid, respectively.
