It was observed for the DPPH method the minimum average
values (g fruit/g DPPH) for the green stage representing the highest
antioxidant activity.
For the ABTS+ 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.
The higher antioxidant activity for green fruits was also
observed in fruits of Malpighia emarginata
