The Polyphenolic Composition of Extracts Derived from Different Greek Extra Virgin Olive Oils Is Correlated with Their Antioxidant Potency

Table 4

The concentrations at which the tested OO extracts exhibited cytotoxicity assessed with the XTT assay and the range of the extract concentrations used for the evaluation of cell redox status. 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. HT: hydroxytyrosol; T: tyrosol. The cytotoxicity (%) at the cytotoxic concentration has been calculated compared with the control.
