对印度洋2种红藻、波罗的海2种褐藻和1种绿藻的脂肪酸组成和含量进行了研究。脂肪酸的定量是通过其香豆酯的高效液相色谱(HPLC)进行的。总脂肪酸含量为220微克1D.W。在红藻中，印度红藻的摄入量为12 600微克·g·1D.W.在红藻Acantophora spicifera中。在这些物种中，特定脂肪酸的比例差别很大。棕榈酸(16：0)在所调查的所有物种中占主导地位(58-68%)，但印度棉仅占11%。波罗的海绿藻枝梗的亚麻酸含量较高(16.7%)，而印度洋红藻含有大量二十碳五烯酸(13%)和油酸(11%)。
Two species of red marine macroalgae (Rhodophyceae) from the Indian Ocean, two species of brown marine macroalgae (Phaeophyceae) and one species of green marine macroalgae (Chlorophyceae) from the Baltic Sea were examined for fatty acid composition and content. Fatty acids were quantified by means of high performance liquid chromatography (HPLC) of their coumaryl esters. The total fatty acid content ranged from 220µg g 1 d.w. in red algae Grateloupia indica to 12 600µg g 1 d.w. in red algae Acantophora spicifera. The proportions of particular fatty acids varied considerably in these species. Palmitic acid (16:0) was dominant in all the species investigated (58–68%) except for G. indica, which contained only 11% of this acid. The Baltic green algae Enteromorpha clathrata was characterised by a high amount of linolenic acid (16.7%), whereas the red macroalgae from the Indian Ocean A. spicifera contained large amounts of eicosapentaenoic acid (13%) and oleic acid (11%).
