ABSTRACT

Extra virgin olive oils (EVOOs) from the fruits of Italian autochthonous varieties Tonda di Villacidro, Tonda di Cagliari, Semidana, and Bosana were investigated to promote their quality aspects. All the analyzed EVOOs showed low values of acidity (≤0.45%) and of peroxide value (≤6.22 mEq O2/kg). There were no relevant differences in fatty acids and triacylglycerols composition among the four EVOOs. Tocopherols determined by HPLC-FL revealed that Bosana oil was characterized by the highest -tocopherol level (213.3 ± 55.4 mg/kg). Chlorophylls, carotenoids, and total phenol (TP) contents as well as antioxidant activity (FRAP, DPPH∙, and ABTS∙
