Agen prune had the best antioxidant activity. The statistical analysis showed significant differences (p < 0.05) between the fruits, except for the Agen prune, apricots and figs aqueous and methanolic extracts.
Differences in cultivation region and practices, ripening stage, harvested conditions and seasons could be the most factors for variation of the antioxidant activity (Patthamakanokporn et al., 2008). Moreover, the antioxidant activity depends on the extraction solvent polarity, the techniques of extraction as well as the process and the temperature of drying.
