| Abstract | ||||
| 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 . | ||||
