title: The isolation and identification of some toxic constituents ofAspergillus wentii wehmer.
abstract: Extraction of a maize culture of a toxinogenic strain ofA. wentii led to the isolation and characterization of three anthraquinones, three bianthrones, a xanthone and a benzophenone. The structures were derived from spectroscopic data and were supported by chemical degradation. Of these, emodin, 1,6-di-0-methylemodin, 5-0-methylsulochrine and 1,3-di-0-methylemodin bianthrone were mildly toxic to ducklings.
