Study Activity Antioxidant Alastazantin dye extracted from the shrimp shell

Abstract

Extraction of the pigment was 90 % acetone 79.61µg/g. The effectiveness of anti-oxidation after 24 hours of a dens was estimated and it was found to be proportional with the increasing of the concentration of astaxanthin which ranged from 83.47 -98.7% of 2-20 mg/ml, respectively, at the highest concentration which was higher than, in their effectiveness, the standard astaxanthin and BHT samples and tocopherol-α, which were to 93.76%, 96.75% and 94.50%, respectively, at the highest concentration. Astaxanthin characterized by high strongly reductionist amounted to 275%, which is nearly approach to ascorbic acid that has a value of 278%, while each of BHT, α- tocopherol and citric acid gave reductionist force less than a dye extracted, 200 and 190 and 225%, respectively. The tincture appeared an ability to connect ferrous ion at the highest concentration in the study (89%) which is higher than that of BHT and α- tocopherol which were 44.6% and 45.1% respectively, while EDTA, ascorbic acid and citric acid beat it in the ability to link ferrous ion which were 97.7%, 96.9% and 94%, respectively.The ability to seize the root of the hydroxyl dye was 84.79% which approach that of the ascorbic acid and citric acid (85.45% and 87.39%), respectively, while it was higherthan that of BHT and tocopherol-α that have values of 57.45% and 58.13 respectively.The dye showed a clear ability to seize the hydrogen peroxide starting froma concentration of 12-20 mg/ml, which reached 83.03%-89.67%, surpassing each of BHT, tocopherol-α and ascorbic acid at the highest concentration that have the values 74.05%, 86.41% and 86.92%, respectively, while it was less than the ability of acid Citric to seize the radical of hydrogen peroxide that was 92.29%. Astaxanthinsurpassed, in its ability to seize the radical of the active oxygen,the control samples of BHT, tocopherol-α and ascorbic acid, having values of 87%, 71% and 85%, respectively, while it was slightly lessthan that of citric acid which was 88%.
