Description
Summary:The volatile fraction of the brown alga Cystoseira sedoides (Desfontaines) C.Agardh is prepared from the crude extract through the following three extraction methods: Hydrodistillation (HD), focused microwave assisted hydrodistillation (FMAHD) and supercritical fluid extraction (SFE). The volatile fractions are analyzed by gas chromatography-flame ionization detector-mass spectrometry (GC-FID-MS), the chemical components are identified on the basis of the comparison of their retention indices with literature and their mass spectra with those reported in commercial databases. The chemical composition of the volatile fractions obtained by different extraction techniques fall into three major chemical classes: fatty acids and derivatives, sesquiterpenes, and hydrocarbons and derivatives. Others Compounds belonging to different chemical classes are found in that chemical composition.
