Although free radicals are also involved in the lipid peroxidation
assay, results are not the same as those found for DPPH; thus, for
example, the strongest inhibition of linoleic acid degradation was
found for Picual, Manzanilla Cacereña and Carrasqueña (45.1,
40.1, and 39.4%, respectively). Such results suggest the importance
of the medium and nature of the free radical employed for considering
the antioxidant test (Table 4).
