Fatty acid profile of different species of algae of the Cystoseira genus: a nutraceutical perspective

Nat Prod Res. 2015;29(13):1264-70. doi: 10.1080/14786419.2014.992343. Epub 2015 Jan 2.


The fatty acid (FA) composition of six macroalgae from the Cystoseira genus, namely Cystoseira compressa, Cystoseira humilis, Cystoseira tamariscifolia, Cystoseira nodicaulis, Cystoseira baccata and Cystoseira barbata, was determined. Polyunsaturated fatty acids (PUFA) corresponded to 29-46% of the total FA detected. C. compressa, C. tamariscifolia and C. nodicaulis stood out for their low PUFA/saturated fatty acid, low n-6 PUFA/n-3 PUFA ratios as well as favourable unsaturation, atherogenicity and thrombogenicity indices, suggesting a high nutritional value with potential applications in the nutraceutical industry.

Keywords: Cystoseira; PUFA; brown algae; fatty acids; nutrition.
