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

Conference Report XVI International Symposium on Marine Natural Products | XI European Conference on Marine Natural Products, 1-5 September 2019, Peniche, Portugal. Asparagopsis armata is considered a biological invader and this red alga is in the last few years one of the worst nightmares for Azores coast biodiversity. So efforts to find an economically valuable application are welcome. In this context biological evaluations of its extracts, such as anti-aging, antioxidant and anticholinesterasic activities, were recently presented [1,2]. Naturally, the knowledge of this species chemical composition is utmost importance not only to find some valuable utilization but also to discovery its mechanisms of defence that can explain its invasive behaviour. In our effort to contribute to this problem solution we establish the GC-MS and UHPLC-MS profiles of both the non-polar and polar extracts. The main compounds in the lipophilic extract were palmitic acid and 1-monopalmitin and brominated compounds dominate both extracts. The detailed results will be presented and discussed in the presentation. info:eu-repo/semantics/publishedVersion
