Currently there is a marked interest in the search for antioxidants from natural sources, including seaweed. For approximately twenty years, the Pharmacology and Toxicology Group of Faculty of Biology (UH) has investigated several species of seaweed, including the red algae Bryotahmnion triquetrum (S. G. Gmelin) Howe, as natural antioxidants. The objective of this work was to analyze the set of these results, which will allow us to define the antioxidant properties of the red seaweed B. triquetrum, propose possible mechanisms of action and, in turn, relate these mechanisms to the chemical composition. In the studies of the chemical composition, the phenolic acids t-cinnamic, p-coumaric and ferulic were identified, molecules that could explain the antioxidant activity. The antioxidant properties were studied with in vitro techniques, in total 7 experimental procedures, which allowed defining these properties and postulating possible mechanisms of action.
