Chemical Constituents of Stereum subtomentosum and Two Other Birch‐Associated Basidiomycetes: An Interspecies Comparative Study

Abstract: Metabolites of the wood-rotting fungus Stereum subtomentosum Pouzar (Basidiomycetes, order Russulales, family Stereaceae) occurring on birch (Betula pendula Roth) trees were phytochemically investigated for the first time. Three main metabolite chemotypes present in MeOH extracts of the fruit bodies, viz. steroids, fatty acids, and water-soluble sugars, were fractionated, isolated, and identified by 1D/2D NMR-spectroscopic analyses, NMR data comparisons, and chemical correlations combined with GC/MS experiment… Show more

“…Comprehensive analyses of the chemical composition of the F. betulina fruiting body carried out under different conditions (Grishin et al 2016; Hybelbauerová et al 2008; Reis et al 2011) revealed the presence of 17 fatty acids, in it 22% saturated and 78% unsaturated (mainly oleic and linoleic acid); sugars ( d -arabinitol, d -mannitol and α,α trehalose); biomolecules with antioxidant properties (tocopherols—0.578 mg/100 g dw, mainly β and γ; ascorbic acid—87.5 mg/100 g dw; β-carotene and lycopene). Among other identified compounds were betulinic acid, betulin, lupeol, fomefficinic acid, ergosterol peroxide, and 9,11-dehydroergosterol peroxide (Alresly et al 2016; Jasicka-Misiak et al 2010).…”

“…The unsaturated fatty acids 9,12‐octadecadienoic acid ( i17 ) and 9‐octadecenoic acid ( i19 ) as well as the saturated fatty acid hexadecanoic acid ( i18 ) were already described in birch wood, while the unsaturated fatty acids i17 and i19 were also found in methanolic extracts of birch‐associated basidiomycetes . The identity of these substances was again verified by measuring an authenticated reference substance.…”
