Abstract
A antioxidant activities of red sumac fruits (semi ripe) (Rhus coriaria) extracts were evaluated and compared with Butylated Hydroxy Toluene (BHT) as a positive control compared sample by using reducing power test, B-Carotene bleaching test, Hydrogen peroxide scavenging activity test and FTC (Ferric thiocyanate) assay. Red sumac fruits were extracted with different solvents (methanol, ethanol, aceton, diethyl ether, ethyle acetate and hexan). The properties of extraction solvents significantly affected extraction yield ,total phenolic compounds and antioxidant activity of red sumac extract, methanol(80%) gave highest extracted yield from red sumac fruits. Also methanolic extract showed highest content of total phenolic compounds compared with other extraction solvents used in study. The methanolic cude extract of red sumac fruits had better antioxidant activity compared with samples treated with extracts by other extraction solvents. The antioxidant activities could be arranged as follow :BHT Keywords Antioxidant activity --- Red Sumac --- Extraction solvent --- الفعالیة المضادة للاکسدة، السماق الاحمر، مذیبات الاستخلاص
