Volatile compounds from the fruiting bodies of beefsteak fungus Fistulina hepatica (Schaeffer: Fr.) Fr.

The volatile compounds from the fruiting bodies of wild Fistulina hepatica (Schaeffer: Fr.) Fr. were isolated by continuous liquid liquid extraction (CLLE), and investigated by high resolution gas chromatography-mass spectrometry (HRGC-MS), GC-atomic emission detector (GC-AED), and gas chromatography-olfactometry (GC-O). Forty eight major volatile compounds were identified and semi-quantified. 11 odorous compounds significantly contributed to the overall flavour of F. hepatica: 1-octen-3-one, 1-octen-3-ol, linalool, phenylacetaldehyde, butanoic acid, an unidentified volatile compound with mouldy odour, (E)-2-methyl-2-butenoic acid, (E)-methyl cinnamate, (Z)-9-hexadecenoic acid methyl ester, bisabolol oxide B and phenylacetic acid.
