SINOPSIS

Qualitative and quantitative analyses of the free fatty acid (FA) composition of ethanol extracts obtained from mycelia of 30 genetically identified strains of 18 species of coprinoid mushrooms (CMs) or coprini belonging to clades Coprinellus (C. bisporus, C. curtus, C. disseminatus, C. domesticus, C. ellisii, C.flocculosus, C. micaceus, C. aff radians I, C. aff radians II, C. aff radians III, C. xanthothrix, Coprinellus sp. 4), Coprinopsis (C. cinerea, C. cothurnata, C. gonophylla, C. lagopides, C. maysoidispora, C. strossmayeri), and Coprinus (C. comatus) were evaluated using gas chromatography. Two unsaturated (lineolic, oleic) and 3 saturated (palmitic, stearic, myristic) FAs were detected in the tested mycelial samples. Amounts of unsaturated FAs prevailed over saturated FAs. Lineolic and palmitic acids were detected in all the species in high quantities (up to 64.73% and 53.82%, respectively). All 5 FAs were found in the Coprinus clade (family Agaricaceae) as opposed to the Coprinellus and Coprinopsis clades (family Psathyrellaceae). Based on the unsaturated and saturated FA content, the species from the clade Coprinellus were different from Coprinopsis species and C. comatus. The obtained data confirm that palmitic, linoleic, and stearic acids are predominant in mushrooms, including coprini. The presence of large amounts of unsaturated FAs in the tested coprini make them an option for further studies to formulate novel mushroom-based dietary supplements and nutriceuticals.
