The strongest antioxidant capacity was found in Sango, with ORAC values at more than double those measured for broccoli and Tuscan black kale. In spite of the varied composition of the phenolic pool, we observed a linear correlation of ORAC values with total phenols: the regression line shows the following equation y = 45.62x − 147.03 and r2 was 0.9915 (data not shown).
