GC- and UHPLC-MS Profiles as a Tool to Valorize the Red Alga Asparagopsis armata

Asparagopsis armata Harvey is a red alga native from the southern hemisphere and then introduced in Mediterranean Sea Atlantic Ocean, including Azores Archipelago, where it considered an invasive alga. Some studies show that extracts exhibit antimicrobial antifouling activities, incorporated some commercialized cosmetic products. (e.g., Ysaline®). However, knowledge of this species chemical composition scarce. The GC-MS UHPLC-MS profiles both nonpolar polar were established to contribute problem solution. According results, A. rich great structural variety halogenated lipophilic aromatic compounds, them identified here for first time. In extract, 25 compounds are identified, being fatty acids, two major compound families, corresponding 54.8% 35.7% (224 147 mg/100 g dry algae, respectively). 1,4-dibromobuten-1-ol palmitic acid most abundant (155 83.4 extract demonstrated richness brominated phenolics, which cinnamic derivatives predominant. results obtained herein open new perspectives valuing as source consequently improving its biotechnological economic potential. Promoting seaweed consequent increase demand will biodiversity conservation ecosystem sustainability.
