oa South African Journal of Chemistry - Investigation of a toxinogenic strain of Aspergillus ustus: the structure of 8-deoxy-6-O-methylversicolorin A and of four new xanthones

 

Abstract

Extraction of maize inoculated with a culture of Aspergillus ustus led to the isolation of new metabolites, viz. three substituted 3a, 12a-dihydro[3',2':4,5]furo[3,2-b]xanthen-5-one derivatives, together with 7-chloro-2-(3-furyl)-1,3,8-trimethoxyxanthone, 8-deoxy-6-O-methylversicolorin A, and the austalides. In addition, the following known metabolites were identified: austocystins A,B,D, and H, averufin, averufanin, and versicolorin C.
