title: Anthraquinones in the biosynthesis of sterigmatocystin by Aspergillus versicolor.
abstract: 14C-labeled averufin, versiconal hemiacetal acetate, and versicolorin A were efficiently converted to sterigmatocystin by Aspergillus versicolor, thus providing experimental evidence that these anthraquinones are biosynthetic precursors of sterigmatocystin, a xanthone.
