Table 3

IC₅₀ values of the tested OO extracts as calculated for the ABTS^⋅+ and plasmid relaxation assays. The results are expressed as (). OLE17 and OLE19 are HT-rich olive oils. OLE05 is a T-rich olive oil, and OLE20 and OLE50 are olive oils with an equal amount of HT and T. Means without a common letter are significantly different (). HT: hydroxytyrosol; T: tyrosol.
