Fatty acid profile of Cystoseira C. Agardh (Phaeophyceae, Fucales) species from the Tunisian coast: Taxonomic and nutritional assessments

A screening of the total lipids and fatty acids (FAs) of 11 brown algae species of the genus Cystoseira (Phaeophyceae, Fucales) from the Tunisian coast is presented and discussed. Cystoseira species showed low total lipid content, ranging from 19.8 to 68.2 mg·g–1 dry weight. Fourteen major FAs were...

Agardh (Phaeophyceae, Fucales) de la costa tunecina: Evaluaciones taxonómicas y nutricionales Bouafif, Cyrine Messaoud, Chokri Boussaid, Mohamed Langar, Habib A screening of the total lipids and fatty acids (FAs) of 11 brown algae species of the genus Cystoseira (Phaeophyceae, Fucales) from the Tunisian coast is presented and discussed. Cystoseira species showed low total lipid content, ranging from 19.8 to 68.2 mg·g–1 dry weight. Fourteen major FAs were detected in the lipid extract of Cystoseira. The FA profile of lipid extracts was characterized by high amounts of saturated FAs (SFAs) ranging from 40.51% to 57.91% of total FAs, with predominance of the lipid fraction of palmitic acid (>30% of total FAs). The arachidonic acid (C20:4n-6) levels were found to be significantly high, ranging from 8% to 16% of total FAs. Multivariate analyses of FA composition showed low geographic differentiation, providing further evidence of intraspecific diversity. Cystoseira crinita, Cystoseira schiffneri, Cystoseira amentacea var. stricta, and Cystoseira sedoides stood out for their low polyunsaturated fatty acid (PUFA)/SFA ratios, low n-6/n-3 PUFA ratios, high unsaturation, and low atherogenicity and thrombogenicity indices, suggesting high nutritional value. Aquí se presenta y discute un análisis de los lípidos totales y ácidos grasos (AG) de 11 especies de algas pardas del género Cystoseira (Phaeophyceae, Fucales) de la costa de Túnez. Las especies de Cystoseira mostraron un contenido lipídico total bajo que osciló entre 19.8 y 68.2 mg·g–1 de peso seco. Se detectaron 14 AG mayoritarios en el extracto lipídico de Cystoseira. El perfil de AG de los extractos de lípidos estuvo caracterizado por altas cantidades de AG saturados (AGS) que variaron de 40.51% a 57.91% del total de AG, con predominio de la fracción lipídica del ácido palmítico (>30% del total de AG). Los niveles de ácido araquidónico (20:4n-6) fueron significativamente altos, y variaron entre el 8% y el 16% del total de los AG. Los análisis multivariados de la composición de AG mostraron baja diferenciación geográfica, lo que aporta más evidencia de diversidad intraespecífica. Cystoseira crinita, Cystoseira schiffneri, Cystoseira amentacea var. stricta y Cystoseira sedoides destacaron por presentar bajas relaciones de ácidos grasos polinsaturados (PUFA)/AGS y PUFA n-6/n-3, alta insaturación y bajos índices de aterogenicidad y trombogenicidad, lo que sugiere un alto valor nutricional.
