Özet:

Edible species of mushrooms, which grow naturally and have important ecological tasks, are collected and consumed as foodstuff in our country as well as in many regions of the world. Many studies to determine the chemical structure of the mushrooms have revealed that they are valuable nutrient sources in terms of essential fatty acids, essential amino acids, vitamins and minerals. It is especially preferred by people who are dieting because they are poor in terms of calories and fat. The aim of this study was to determine the fatty acid contents of Cyclocybe aegerita (V. Brig.) Vizzini and Hygrophorus eburneus (Bull.) Fr. mushrooms samples collected from natural environment. Mushroom samples, which are the material of our study, were collected in Tokat during field trips. The analyzes were performed by GC-MS instrument (Agilent 7890 GC/5970 MS Series-SantaClara, CA, USA) after obtaining methyl esters of fatty acids. At the end of the studies, palmitic (C16:0), stearic (C18:0) , oleic (C18:1) and linoleic acid (C18:2) from C. aegerita samples; myristic (C14:0), palmitic (C16:0), palmitoleic (C16:1), stearic (C18:0), oleic (C18:1), linoleic (C18:2), and nervonic acid (C24:1) from H. eburneus samples were determined in different proportions. The highest amount of fatty acid was found linoleic acid in C. aegerita with proportions of 54.33% and oleic acid in H. eburneus samples with proportions of 47.80%. In addition to also in the both mushroom species, total saturated fatty acid rate was higher than total un saturated fatty acid rate.
