Abstract Current in vitro methodologies neglect or subestimate the contribution of betalains to antioxidant capacity foods because they do not reflect their vivo biological mechanisms. In this study, we assessed sensibility lipoxygenase-fluorescein (LOX-FL) method towards betalains, phenolic compounds and ascorbic acid from Opuntia spp. fruits; (ii) peel pulp extracts ficus-indica L. Mill (var. Fresa, Colorada Blanco) stricta var. Dillenii ; by comparing LOX-FL traditional methods (ORAC TEAC). The spectrophotometric monitoring reaction avoided interference caused betalain pigments. Indicaxanthin betanin showed high antiperoxidative radical scavenging mechanisms assay. O. tissues highest which correlated with content. ORAC TEAC were less sensible activity. To our knowledge, is first time has been used on betalain-rich foods. Graphical
