TAA of carotenoids. (A) Data are expressed as equivalent of micromoles of Trolox and reported as the mean ± SD of three independent experiments (°°° p < 0.001 vs. fucoxanthin, Student’s t-test); (B,C) SH-SY5Y cells were treated for 2 h with the studied carotenoids at a concentration of 5 µM. At the end of treatment, the ABTS radical scavenging activity was evaluated in the membrane and cytoplasmic fractions using the ABTS assay. Data are expressed as equivalent of the micromoles of Trolox per milligram of protein and shown as mean ± SD of three independent experiments (°° p < 0.05 and °°° p < 0.001 vs. cells treated with fucoxanthin; ** p < 0.01 and *** p < 0.001 vs. untreated cells, one-way ANOVA with Tukey post hoc test).
