摘要：

The red pigments, auxarconjugatins A, B and C, were isolated from mycelia of Auxarthron conjugatum, an ascomycetous fungus belonging to the Onygenaceae, in which the causative fungi of severe mycoses also belong. The structures of auxarconjugatins A, B and C, including the stereochemistry of the conjugated tetraene, were established by spectroscopic analyses. These compounds were in equilibrium with a few double bond stereoisomers of the double bonds when dissolved in MeOH or MeCN. (C) 1999 Elsevier Science Ltd. All rights reserved.
