This  work was achieved to study the antioxidant activities of ethanolic extracts of four fruits, physalis peruviana L.( pp ), Ziziphus spina-christi (z c ), Syzygium cumini (s c) and Eriobotrya japonica (E j) using in vitro antioxidant methods and determine the total phenolic compounds (TP) , flavonoids (F), total tannins( TT) and flavonols( FL) contents in fruits ethanolic extracts. Syzygium cumini (Sc) extract gave the highest contents of TP,F, TT ,  and FL contents. Also, Syzygium cumini (Sc) extract gave the highest total antioxidant activity, reducing power, scavenging activity of H₂O₂ radical, superoxide radical, DPPH radical, and the highest metal chelating activity followed by Eriobotrya japonica (E j) extract, Ziziphus spina-christi (z c) extract and physalis peruviana L.( pp) extract respectively .
