Abstract

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.

温带和热带褐藻的脂质、脂肪酸和岩藻黄质含量
褐海藻脂质部分含有Fx、多酚和n-3 PUFA等多种生物活性成分。本研究对从冷水和温水中收获的褐藻进行了总脂、Fx和FA组成的测定。研究的7种褐藻是在不同的月份从两个不同的地理区域收集的,即冷水(日本)和温水(印度尼西亚)。结果表明,温带褐藻的总脂质和岩藻黄质含量高于热带褐藻。温水海藻PUFA含量以16:0、18:1n-9、20:4n-6为主,冷水海藻以16:0、20:4n-6、20:5n-3为主。温带褐藻[S.]horneri (Turner) J. Agardh]富含岩藻黄质和n-3 PUFA,尤其是EPA。
