Studying the Properties of the Active Compounds Extracted from the Seeds of Some Root Plants and the Effect of Preserving Sun Flower Oil

This study included the selection of rapeseed seed (Brassica rapa) and radish seed (Raphanus sativus) to estimate the antioxidant activity , the estimation of the amount of phenols , flavonoids ,their ability to bind iron ion , the reduction power and the capture of hydrogen peroxide of these alcoholic and water extracts the extraction process was carried out in two water extraction methods with boiling water for 24 hours and ethanol extraction with 98% ethanol for 24 hours at laboratory temperature 23 - 25°C , Alcohol extraction of rapeseed seed in phenols was 68.16 mg / g / calic acid, in addition, while alcohol extraction of rapeseed seed content of flavonoids was 8.95 mg / g the lowest amount of flavonoids in water extraction of radish seed was 2.36 mg / g, the alcohol extract of the radish surpassed its antioxidant efficiency %90.41 in addition, the highest correlate was found in the radish extract of radish %81.45 compared to the bond of ferrous 87.2% EDTA and citric acid %86.2 the water extraction of radish seed has a hydrogen peroxide capture capacity of 67.8% compared to ascorbic acid % 87.75. And extract of Radish seed and Rapeseed during the 90 day storage period (5.67, 5.41, 3.52, 3.48) and (7.51, 6.50. 5.38. 4.33) mEq / kg respectively . The result of the inhibition of the added extract of Radish seed and Rapeseed concentrations ( 0.1, 0.15, 0.2%), oil to inhibit the oxidation of Sunflower oil as it exceeded the reduction of peroxide values during the reservoir periods (15, 30, 60, 90) d at 70°C temperature
