Lipids, Fatty Acids, and Fucoxanthin Content from Temperate and Tropical Brown Seaweeds

Brown seaweeds lipid fraction contains several bioactive components such as Fx, polyphenol and n-3 PUFA. In this research, total lipids, Fx and FA compositions of brown seaweeds harvested from cold waters and warm waters were evaluated. The seven brown seaweeds studied were collected in different months from two different geographical areas, viz. cold waters (Japan) and warm waters (Indonesia). The result show that total lipid and Fucoxanthin in temperate brown seaweeds were higher than tropical brown seaweeds. The major PUFA from warm water seaweeds were 16:0, 18:1n-9, 20:4n-6, and cold water continued dominantly 16:0, 20:4n-6, 20:5n-3. Temperate brown seaweeds [S. horneri (Turner) J. Agardh] was rich in fucoxanthin and n-3 PUFA especially EPA.
