To provide a theoretical basis for the Sargassum species in feeding nutrition and food application,the differences of the volatile components in different parts of three common species of the genus Sargassum were compared. The volatile components in different parts of Sargassum fusiforme,Sargassum thunbergii and Sargassum horneri were analyzed by solid-phase micro-extraction (SPME) and gas chromatography-mass spectrometry (GC-MS).A total of 68 volatile compounds were identified from three species of the gen...
