Results were the mean ± SD (n = 3) on a dried weight (g) of citrus basis. Total phenolics were calculated as mg gallic acid equivalents (GAE)/g DW. Antioxidant capacities (DPPH, FRAP, ORAC and CUPRAC) were calculated as mg trolox equivalent antioxidant capacities (TEAC)/g DW. Values within each column followed by different superscript letters were significantly different (p < 0.05) according to Tukey’s tests. * Antioxidant index score = [(sample score/best score) × 100], averaged for all four tests for each cultivar for the antioxidant potency composite (APC) index. # Ranked according to the APC index.
