It was observed for the DPPHradical dot method the minimum average values (g fruit/g DPPHradical dot) for the green stage representing the highest antioxidant activity. For the ABTSradical dot+ method the highest results were obtained for the fruits on the green stage, that gives also higher antioxidant activity at this stage. This result can be justified by the highest content of extractable polyphenols, total anthocyanins, yellow flavonoids and in the activity of the antioxidant enzymes of the fruits in the green stage.
