Components of the wood-rotting fungus Sarcodontia setosa

Abstract

From the wood-rotting fungus Sarcodontia setosa (Pers.) DONK a mixture of benzoquinone acids was obtained which was converted to methyl esters Ia-IIIa and separated by preparative HPLC. The presence of the known sarcodontic acid (II), i.e. 15-(6-methoxy-1,4-benzoquinon-2-yl)-2-pentadecenoic acid, and further of 15-(6-methoxy-1,4-benzoquinon-2-yl)pentadecanoic acid (I) and 15-(6-methoxy-1,4-benzoquinon-2-yl)-2,5-pentadecadienoic acid (III) was proved in the mixture. The structures were determined by spectral methods.
