AB Phenolic compounds can be considered as the most important bioactive compounds in Mediterraneandiet. However, many of the complex connections between phenols antioxidant reactivity and their molecularstructure remain unsolved. To shine light on these issues, the antioxidant reactivity of 15 relevant phenoliccompounds was studied. Two different analytical approaches were combined: (a) the well-established 2,2-diphenyl-1-picrylhydrazyl (DPPH·) stable free radical assay, and (b) the 2,3-diazabicyclo[2.2.2]oct-2-ene (DBO)fluorescent probe assay. The results obtained confirm how certain structural features (i.e., hydroxyl and methoxygroups, alkyl and alkenyl chains) play a critical role in the singular antioxidant response exhibited by eachphenolic compound. This knowledge provides decisive information to select a specific phenolic compound asan antioxidant additive or for the chemical design of new antioxidants.
