Özet:

Algae are seen as an important source of long-chain polyunsaturated fatty acids (PUFA), especially γ-linolenic acid, arachidonic acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is thought that the fatty acids obtained from these organisms can be used in the treatment of hypertension, heart and autoimmune diseases and in the prevention of cancer. High valence compounds obtained from algae; Oils, fatty acids, proteins, carbohydrates, pigments, minerals, vitamins, sterols, antioxidants and some other bioactive polyphenols are used in many fields in the pharmaceutical, cosmetic, food and health sectors. Species belonging to the Bacillariophyta division are single-celled siliceous algae that live cosmopolitanly in all aquatic and humid environments on earth. They contain high levels of silicon. With these properties and specific compounds such as levosine, it has valuable use in pharmaceutical, food and biomedical sciences. Diatoms are remarkable organisms with their highly ornamented morphological structures. In this study, fatty acids of Gomphonema olivaceum, which was isolated and cultured from the benthic habitats of the Tokat Yeşilırmak River, were investigated. As a result of the chromatographic analysis, a total of 24 essential fatty acids were determined (some in trace amounts and some in high proportion). Of these, C16:0 Palmitic acid (32.04%) and C16:1 Palmitoleic acid (30.97%) were measured at high rates. C18:0 Stearic acid (6.93%), C14:0 Myristic acid (6.17%) and C20:0 Arachidic acid (5.03%) were recorded as relatively higher than the others.
