标题：Metabolic Products of Fungi. XI. Some Observation on the Occurrence of Skyrin and Rugulosin in Mold Metabolites, with a Reference to Structural Relationship between Penicilliopsin and Skyrin.
摘要：1) It was shown that Sepedonium ampullosporum DAMON produces rugulosin, skyrin, and chrysophanol. 2) Skyrin and emodin were found to be produced by Penicilliopsis clavariaeformis SOLMS-LAUBACH along with penicilliopsin. 3) On oxidation with selenium dioxide, penicilliopsin was directly converted into skyrin.
