Abstract
Fish oil is one of the important products obtained from marine aquatic organisms. It is widely used for both industrial and medical purposes. The chemical composition of fish oil, as well as other substances of a lipophilic nature, is traditionally divided into saponifiable and unsaponifiable fractions containing mono-, di- and triacylglycerols of higher fatty acids, phospholipids, steryl esters, sterols and free fatty acids. In studies of both freshwater and ocean fish oils, marine fish oils have been found to contain 35 unsaturated fatty acids with between 1 and 6 double bonds. The aim of this study is to conduct a comparative analysis of the qualitative and quantitative content of fatty acids in samples of the preparation “fish oil for internal use” of the Russian production of Tula Pharmaceutical Factory LLC. The objects of study were: samples of fish oil of 2 series, A and B, Russian-made LLC Tula Pharmaceutical Factory. Fish oil is a fatty oil obtained from the liver of fish, approved in the state Pharmacopieia and used as a medicine venous means. For qualitative and quantitative analysis, a TRACE GC Thermo Fisher Scientific gas chromatograph was used. The analyzed samples of fish oil do not meet the requirements of the state pharmacopoeia XIV.
