The ash, moisture, protein and carbohydrate content of the extracted oil were estimated as 4, 7, 4 and 1% respectively. The Vitamins A and E was found to be 59.14 and 17.4 mg/100 g. Nine fatty acids were found and the Linoleic acid, DHA and EPA were recorded as higher. The specific gravity, solidification point, refractive index, saponification value, iodine value and acid value were also calculated and found as 1.056, 1.2 °C, 1.465 µ, 50.5, 20.4 mg and 0.075 mg KOH/g. The antioxidant activity that includes total antioxidant activity, DPPH & Hydroxyl radical scavenging assay, reducing power and ferrous ion chelating activity of liver oil was studied by following standard methods and results of all the assays was found increasing with increase in concentration. Further purification of liver oil and studying its antioxidant property in animal model shall form the basis for its use as a potent alternate natural antioxidant and nutrition supplements.
