Determination of Fatty Acid Composition, Cholesterols, Triglyceride and Vitamin Contents of Some Selected Fishes from Assam, India

Abstract

Background: Fishes are good sources of the fatty acids such as ω-3 and ω-6 polyunsaturated fatty acids, and fat-soluble vitamins for human consumption which play vital roles for various biological processes in the body and help in the proper growth and prevention of diseases. Objective: The objective of the present study was to determine the fatty acid composition, cholesterols, triglyceride and vitamin contents of some selected fishes from Hel river, Assam, India. Methods: Fatty acid composition of fish species was examined using gas chromatography-mass spectrometry, lipid components were determined following the reported methods and vitamins A and D contents were investigated by reversed-phase high-performance liquid chromatography. Results: Fatty acid compositions varied from 51.20-89.47% of saturated fatty acids, 0.27-19.68% of monounsaturated fatty acids and 1.75-30.76% of polyunsaturated fatty acids. Eicosapentaenoic acid and docosahexaenoic acid ranged from 0.54-22.30% and 1.26-18.85%, respectively. The fish species showed varying amounts of lipid components. The vitamins A and D were found in the range of 15.85-1287.0 μg/100 g and 45.0-677.24 μg/100 g, respectively. Conclusion: The fish species of this study are found rich in ω-3 polyunsaturated fatty acids such as eicosapentaenoic acid and docosahexaenoic acid along with noticeable amounts of vitamins A and D. Hence, these fish species have the potentials to serve as the natural dietary supplements for ω-3 fatty acids and other nutrients.

Fatty Acids Composition of Two Commonly Consumed Freshwater Fishes (Clarias gariepinus and Chrysichthyes nigrodigitatus) from the Cross River at Ahaha, Obubra, Nigeria

“…Saturated, monounsaturated and polyunsaturated fatty acids were detected to be higher in C. gariepinus > Pseudotolithus typus > Pentanemus quinquairius > Tilapia zilli from Lagos lagoon [20]. Sarkar et al [23] reported that the most abundant fatty acids usually found in ten freshwater fishes of Hel river of Assam, India are myristic, palmitic, oleic, linoleic EPA and DHA acids. The major SFA (palmitic, Stearic and behenic acids), MUFA (oleic acid) and PUFA (linoleic acids) were reported four fishes of Hooghly estuary, West Bengal, India [24].…”

“…Ljubojevic et al [27] stated that "PUFAs in some fishes from Inland waters which varied from 17.07 to 28.15 %. Linoleic acid (omega -6) detected in nine fish species and was found to be the most abundant PUFAs and varied from 0.32 % in T. putitora to 27.21 % in N. Hexagonolepis" [23].…”
