Abstract:
The Irans coastal marine algae have great potential in the fields of medicine, food and cosmetics which unfortunately, fewer have been studied. In the present study, Total lipid and fatty acid profile of brown algae, N. zanardini were measured in both cold and warm season. The total lipid content with 41.1±0.8 mg/g dry weight was high in February. In the present study, Fatty acid composition of lipids showed that Palmtic acid (C16:0), in both seasons, was the main fatty acid, with 40.27±1.51% in June and 40.49±0.23% in February. In both season the amount of Arachidonic acid (AA) was higher than Eicosapentaenoic acid. Total saturated fatty acid (SFA) in tow season do not showed significant changes, while total monounsaturated fatty acid (MUFA) in July showed a lower amount and total polyunsaturated fatty acid (PUFA) increased in February. The ratio between omga6 to omga3 in both cold and warm season was: 1.14:1 and 1.50:1 respectively, which higher than the cold and temperate zones species. In general, the seaweed N.zanardini, collected in February has higher total lipid and polyunsaturated fatty acids in comparison with July, but the variation of fatty acid and total lipid in compared with temperate zones species is not so tangible.
