Fatty Acid Composition, Antioxidant Activity and Thrombolytic Activity Analysis of Extracted Lipid from Colisa fasciatus

As Bangladesh is enriched with fish resources of fresh water, few studies have been conducted to reveal the nutritional value of fish oils. In our present work, we aimed to study the composition of extracted lipids from Colisa fasciatus to explore the medicinal value of this fish which can be used as a precursor for nutraceuticals also. The lipid was extracted from the fish using a solvent extraction method with chloroform and methanol. The qualitative parameters like acid value, peroxide value, saponification value and iodine value were calculated by chemical reaction methods. GCMS analysis was carried out to explore the composition of the extracted lipid. The antioxidant activity of the extracted lipid was carried out by DPPH radical scavenging and Iron reducing study. Thrombolytic activity of the sample was studied by weight difference method. Among 20 constituents hexadecanoic acid (42.808%) was present in the highest concentration. The other remarkable components are Methyl tetradecanoate, pentadecanoic acid, heptadecanoic acid and 9-Octadecanoic acid. Compared to butylated hydroxyl toluene (BHT) as standard, our extracted fish lipid showed 27.9% removal of DPPH. The thrombolytic property showed 7.07 % lysis of blood clots. The fatty acid composition of the extracted lipid supports physiological properties like antiaging and thrombolysis which can make a way to find a new array to use this fish lipid as a new nutritional supplement.
