Abstract
In this study, total polyphenol ,flavonoid , anthocyanin and ascorbic acid contents were determined in black (Morus nigra L.) and white (Morus alba L ) mulberry fruits grown in Egypt . Antioxidant activity , reducing power and antidiabetic effect were determined in fruits methanolic extract . The total polyphenols ranged from 114.88 to 417.37 mg GAE/g dry weight in black and white mulberry fruits , respectively . While total flavonoids ranged between 12.43 and 24.27 mg QE/g d.w., respectively . Black fruits contain a higher value of anthocyanins 19.33 than white fruits 1.36 mg as cyanidin–3–glucoside, respectively. Both Black and white fruits contain nearly the same values of ascorbic acid 35.61 and 36.74 mg/100g .d.w. Black fruits methanolic extract have higher values of antioxidant activity inhibition % and reducing powerthan that obtained from white fruits . Average value of 76.908 % , 0.172 at 100 mg / ml ; 69.084 % and 0.085 at 100 mg / ml for black and white fruits , respectively .The effect of black and white fruits methanolic extracts were investigated on STZ diabetic rats through the determination of serum glucose , total cholesterol , triglycerides and liver functions (ALT and AST) .The best results were observed for black mulberry fruits methanolic extract .
