Abstract: This work aimed to measure the efficiency of numerous organic solvents such as, methanol, ethanol, dichloromethane, acetone, hexane and ethyl acetate for extraction of ( flavonoids and polyphenolic compounds(TFC and TPC respectively) from the orange peel. As well, the effect of the solvents on the yield percentage, chelating activity, antioxidant/radical scavenging capacity and reducing electricity ability from the produced extracts were looked into. The outcomes revealed that all extracts of the orange peel exhibited variable antioxidant activity. Specially, the ethanolic extract showed the greatest (p < 0. 05) values for yield (%), TPC, TFC, chelating and antioxidant actions (% DPPH scavenging activity). It is figured, the solvent play a vital role in the removal of the herb constituents. Specifically, methanol and ethanol happen to be high extremely among the solvents used.

Epidemiological were produced in Egypt, comprised 2 . 14 million a great deal of studies upon dietary citrus fruit flavonoids reduce the risk of orange. A large part of this creation is resolved to heart disease [9, 10]. Likewise, it is appealing to more the commercial extraction of citrus juice...
