Abstract
Antioxidants play a very important role in the body defense system against Reactive Oxygen Species (ROS). Antioxidants are an important protective mechanism against ROS. This study highlights the functions of antioxidants in the blood and selected organs associated with health.The present study was conducted to investigate the srtawberrry, goldenberry, white and black mulberry as rich source of anthocyanins and other phenolic compounds with a certified antioxidant activity and spectacular effect in some chronic diseases. In the present work, the fruits srtawberrry, goldenberry, white and black mulberry were analyzed for proximate chemical composition such as moisture, ash, lipids, proteins, fiber, carbohydrates and some reducing and nonreducing sugers, minerals, fatty acids, phenolic compounds, flavonoides compounds, some vitamins (A, E and C), anthocyanin, beta carotenoids, amino acids, total phenolic compounds, quantitative deterimination of antioxidative compounds by (DPPH) and studied effect of antioxidants extracted from srtawberrry, goldenberry, white and black mulberry by rancimat method on the oxidative stability of sunflower oil. The results showed that white mulberry contained 79.34% moisture, 12.98% protein, 9.03% ether extract, 6.36% ash, 8.32% crude fiber and 63.31% carbohydrates, while, the black mulberry contained 76.45% moisture, 10.85% protein, 7.21% ether extract, 4.79% ash, 5.45% crude fiber and 71.7% carbohydrates. On the other hand, goldenberry contained 77.78% moisture, 9.16% protein, 9.95% ether extract, 5.44% ash, 16.32% crude fiber and 59.13% carbohydrates. It could be noticed that strawberry recorded 90.87% moisture, 7.65% protein, 3.74% ether extract, 3.48% ash, 10.32% crude fiber and 74.81% carbohydrates. White mulberry was the highest in potassium (1753.17 mg/100g), while, black mulberry was the highest in iron (366.75 mg/100g). Goldenberry was the highest in calcium (838.10 mg/100g) and phosphorus (400.01mg/100g).Strawberry contained the highest amounts of sodium (586.99 mg/100g), magnesium (190.62 mg/100g), zinc (46.56 mg/100g) and manganese (26.48 mg/100g). White mulberry was showed the highest in stearic acid (13.66 g/100g) and linoleic acid (51.33 g/100g) . On the other hand, black mulberry was the highest in palmtic acid (25.45 g/100g) ,while, goldenberry was the highest in oleic acid (43.41 g/100g).Strawberry recorded the highest level in myristic acid (10.25 g/100g).This study was performed to investigate the industry of strawberry juices and jams containing different ratios of white, black mulberry and goldenberry. The produced juices and jams were analyzed for chemical composition, minerals, vitamins and quantitative deterimination of antioxidative compounds by (DPPH) for high concentrations in juices and jams. This work was aimed also to study the biological effects of these materials on rats blood sugar. The results showed that the diabetic rats were fed for (42 days) on basal diets and take different concentrations of juices caused a marked decrease in blood sugar level comparing with the negative control to become near from the normal rats. As for the function of liver (GOT, GPT and Albumin), function of kidney (urea, creatinine and uric acid) and function of the lipids (TC, TG, HDL-c and LDL-c) in the normal levels were not affected by a significant effect comparing with the negative control.
