| Abstract: | Fruiting bodies were formed around a Penicillium colony which appeared as a contaminant in a culture of Schizophyllum commune, and this phenomenon was reproduced with a synthesized system consisting of S. commune IAM 9006 and P. funiculosum A-l. The active substances were recovered in an acetone extract of the mycelia of P. funiculosum, purified by silica gel column chromatography and reverse-phase high-performance liquid chromatography, and characterized by infrared spectroscopy, gas-liquid chromatography, gas-liquid chromatography-mass spectroscopy and nuclear magnetic resonance spectroscopy. They were ceramides and cerebrosides having nonadecasphingadienine and 2-hydroxy fatty acid moieties in common. The major component was identified as (4E,8E)-N-2′-hydroxy-(E)-3′-octadecenoyl-1-O-β-glucopyranosyl-9-methyl-4,8-sphingadienine. |
