چکیده
|
Seaweeds,or marine macroalgae,are rich in a large variety of natural compounds used in nutritional and pharmaceutical areas. in this study the brown seaweed cystoseira humilis harvested from the atlantic coast of morocco has been investigated for fatty acid (fa) composition as well as for antioxidant and antibacterial potentials. the results revealed that polyunsaturated fatty acids (pufas) of c. humilis represented 47.67% of total fas where arachidonic acid c20:4 (n-6) was the most abundant pufa (18.1%) followed by eicosapentaenoic acid c20:5 (n-3) (11.79 %). c. humilis showed a low ω-6/ω-3 ratio,high unsaturation index (ui=191.42) and low atherogenicity and thrombogenic indices (ai=0.55 and ti= 0.04). moreover,methanol extract of c. humilis exhibited high dpph radical scavenging activity (82%) and a moderate ferrous ion-chelating (fic) ability (68%). the antibacterial activity was limited to staphylococcus aureus and bacillus cereus among all tested pathogenic bacterial strains. in conclusion,c. humilis exhibited promising a fas profile and antioxidant activities which could be further enhanced by isolating these constituents in pure form for nutraceutical and pharmaceutical purposes.
