Abstract-The characteristic volatile constituents of the brown and red marine algae obtained by capillary GC and GC-MS were compared.
2, 3-Dihydrofarnesol, farnesol and farnesal were identified as characteristic volatile com- pounds in Sargassum nigrifolium.
These compounds were not detected in the other marine brown algae and red algae we investigated.
Hexadecanoic acid, tetradecanoic acid, 9-hexadecenoic acid and pentadecanoic acid were identified as the common main volatile compounds.
