Özet

The total lipid and fatty acid methyl esters composition of the some algae collected from coastal zones of the canakkale were determined by Folch method. This method is a conventional lipid extraction procedure using the solvent, chloroform: methanol (2:1 v/v). Fatty acid analyses were made by using gas chromatography. Total lipid percentages ranged from 2.02% (dry weight algae: d.w.) in Lemanea fluviatilis to 9.56% (d.w.) in Batrachospermum gelatinosum. Presence of 33 fatty acids was revealed, of which 13 were saturated and 20 were unsaturated. Nine of unsaturated were monounsaturated and eleven of them were polyunsaturated fatty acids. The major fatty acids identified were palmitic (16:0) and oleic acid (C18:1n9). For the ratio unsaturated/ saturated; Lemanea fluviatilis (2.24) has the highest value and then Dictyota implexa (1.78), Cystoseira barbata (1.59), respectively. Phyllophora crispa has the highest total omega-3 (19.28%), omega-6 (16.6%) and Lemanea fluviatilis has the highest omega-9 (66.01%) values in total fatty acids.
