Antioxidant properties of the red alga collected on the North West Algerian coast.

The aim of the present study was to evaluate the total phenolic and lipid content, fatty acids profiles and antioxidant activities of aqueous and solvent extracts of the red seaweed , through six different investigations. The present study demonstrated that phenol contents (mg gallic acid/g dry weight) were highest in the aqueous and methanolic extracts, followed by the ethanolic, hydroethanolic and hydromethanolic extracts. The lowest phenol contents were identified in the three remaining extracts: Butanolic, petroleum ether and acetone extracts.
