Determination of Fatty Acid content of Pleurotus eryngii (DC.) Quél. Growing in the Aegean Region

Abstract

In this study, it was aimed to determine the fatty acid content of Pleurotus eryngii (DC.) Quél. which grows naturally and is consumed as functional food or dietary supplement by the public in Mugla (Bodrum), Izmir ve Çanakkale. The collected mushroom samples were dried at room temperature and extracted with hexane. The 37 fatty acids were scanned in the content of extract. According to the results obtained with the GC/MSD, 17 fatty acids were determined. Major constituent of Pleurotus eryngii mushroom was found to be oleic acid (48.125%), palmitic acid (14.736%), linoleic acid (14.094%), stearic acid (6.469%) and linolelaidic acid (5.128%) were determined. According to the results obtained, Pleurotus eryngii is an edible wild mushroom that can be used in the food and pharmaceutical industry.

Ege Bölgesinde Yetişen Körek Mantarı (Pleurotus eryngii (DC.) Quél.)’nın Yağ Asidi İçeriğinin Belirlenmesi

Abstract

Bu çalışmada Muğla (Bodrum), İzmir ve Çanakkale çevresinde doğal olarak yetişen ve halk tarafından gıda olarak tüketilen Pleurotus eryngii (DC.) Quél.’nın yağ asidi içeriği belirlenmesi amaçlanmıştır. Toplanan mantar örnekleri oda şartlarında kurutulmuş ve hekzan ile ekstraksiyon yapılmıştır. Elde edilen ekstrakt içeriğinde 37 adet yağ asidi taraması yapılmıştır. GC/MSD cihazı ile elde edilen sonuçlarına göre 17 adet yağ asidi tespit edilmiştir. Sonuçlar incelendiğinde majör bileşen olarak; oleik asit (%48.125), palmitik asit (%14.736), linoleik asit (%14.094), stearik asit (%6.469) ve linolelaidik asit (%5.128) belirlenmiştir. Elde edilen sonuçlara göre Pleurotus eryngii gıda ve ilaç sektöründe kullanılabilecek yenilebilir yabani bir mantardır.
