Abstract: Volatile compounds from Dictyophora echinovolvata Zang, Zheng et Hu fruit bodies were extracted by simultaneous distillation extraction (SDE) and analyzed by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O) with a DB-Wax strong-polar column and a RXT-5 weak-polar column. Totally 74 volatile compounds were identified, including 18 alcohols, 8 aldehydes, 7 acids, 6 ketones, 8 heterocyclic compounds, 5 aromatic compounds and 6 other compounds. Among them the prominent compounds were oxacyclopentadecan-2-one (5.99%), 6,10-dimethyl-5,9-undecadien-2-one (3.06%), 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-ol (2.61%) and benzene acetaldehyde (2.48%). In addition, 10 volatile compounds were identified by gas chromatography-olfactometry, which comprised 1-octen-3-one, 6-methyl-5-hepten-2-one, 2-octenal, 1-(2-furanyl)-ethanone, 5-methyl-2-furancarboxaldehyde, 2-nonenal, caproic acid, cis-geranylacetone, phenylethyl alcohol and 2-acetylpyrrole.

Key words: Dictyophora echinovolvata Zang, Zheng et Hu, simultaneous distillation extraction(SDE), gas chromatography-mass spectrometry (GC-MS), gas chromatography-olfactometry (GC-O), volatile compounds
