Determination of fatty acid profile and mineral contents of Tricholomopsis rutilans collected from Yozgat

Abstract

This study was carried out to determine the content of some minerals and fatty acids in Tricholomopsis rutilans (Schaeff.) Singer samples. Tricholomopsis rutilans is a saprophytic mushroom growing on or around conifer stumps and characterized by white spore print, yellow gills, a large yellow cap and yellow stipe entirely covered with red to purplish red scale and fibrils. It is an edible mushroom, although the taste is not nice. The analysed mushroom samples, were collected from different localities of Yozgat province during field trips between 2012-2016 years. Mineral analysis were performed by ICPMS, and fatty acids were tested by Gas Chromatography-Mass Spectrometry system (GC-MS). Seven different fatty acids (miristic, pentadecanoic, palmitic, palmitoleic, stearic, oleic, and linoleic acid) and six different minerals (Cu, Mn, Zn, Fe, Mg, Na) have been determined in mushroom samples. Oleic and linoleic acid were the major fatty acids with proportions 39.04% and 37.09%, respectively. Na and Mg were found to be the most abundant minerals with 126.895 mgkg-1 and 754.605 mgkg-1 , respectively among the determined minerals.

Yozgat'tan toplanan Tricholomopsis rutilans örneklerinin yağ asidi profili ve mineral içeriğinin belirlenmesi

Abstract

Bu çalışma Tricholomopsis rutilans (Schaeff.) Singer örneklerinde bazı mineral ve yağ asitlerinin içeriğini belirlemek amacıyla yapılmıştır. Tricholomopsis rutilans konifer kütüklerinin üzerinde veya çevresinde gelişen saprofit bir mantardır ve beyaz spor baskısı, sarı jiller ve üzerleri tamamiyle kırmızı-morumsu kırmızı pullar ve fibriller ile kaplı büyük sarı şapka ve sarı sapla karakterize edilir. Tadı güzel olmasa da, yenilebilir bir mantardır. Analiz edilen mantar örnekleri 2012-2016 yılları arasında yapılan gezilerde Yozgat ilinin farklı bölgelerinden toplanmıştır. Mineral analizleri ICP-MS ile yağ asitleri ise gaz kromatografi-kütle spektrometre sistemi (GC-MS) ile test edildi. Analiz sonuçlarına göre mantar örneklerinden yedi farklı yağ asidi (miristik, pentadekanoik, palmitik, palmitoleik, stearik, oleik ve linoleik asit) ve altı farklı mineral (Cu, Mn, Zn, Fe, Mg, Na) tespit edilmiştir. Oleik ve linoleik asit, 39.04% ve 37.09% oranlarla major yağ asitleri olarak belirlenmiştir. Tespit edilen mineraller arasında Na ve Mg’un, 126.895 mgkg-1 ve 754.605 mgkg-1 ’lik oranlarla en bol bulunan mineral mineraller olduğu belirlenmiştir.
