Free ceramides(Cer-1 and Cer-2) and cerebrosides(glucocerebrosides,CMH-1 and CMH-2) were isolatated from the Eringi mushroom, Pleurotus eryngii by successive column chromatography on ion exchange Sephadex(QAE-Sephadex), magnesium silicate(Florisil) and silicic acid(Iatrobeads). By gas-liquid chromatography(GC), gas chromatograph-mass spectrometry(GC-MS) and matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS), their structures were characterized as ;Cer-1 : N-palmitoyl-(16.7%), N-stearoyl-(14.0%), N-behenoyl-(19.2%) and N-lignoceroyl-phytosphingosines(27.7%); Cer-2 : N-2'-hydroxybehenoyl-(22.6%), and N-2'-hydroxylignoceroyl-phytosphingosines(60.5%); CMH-1 : 1-O-glucosyl-N-2'-hydroxypentadecanoyl-(13.8%) and 1-O-glucosyl-N-2'-hydroxypentadecanoyl-nonadecasphingadienines(71.2%); and CMH-2 : 1-O-glucosyl-N-2'-hydroxypentadecanoyl-(15.3%) and 1-O-glucosyl-N-2'-hydroxypalmitoyl-phytosphingosines(84.7%)
