Abstract

Nine mycotoxins including six aspergillic acid group toxins, aluminiumneoaspergillin (1), zirconiumneoaspergillin (2), aspergilliamide (3), ferrineoaspergillin (5), flavacol (6), neoaspergillic acid (7), and three ochratoxins, ochratoxin A n-butyl ester (4), ochratoxin A (8), ochratoxin A methyl ester (9), were isolated from the fermentation broth of marine gorgonian derived fungus Aspergillus sp. SCSGAF0093. Four of them (1-4) were new mycotoxins, and their structures were elucidated on the basis of spectroscopic analysis and chemical evidence. The bio-toxicity of compounds 1-9 were determined by brine shrimp lethality bioassay with median lethal concentration (LC(50)) values of 2.59-205.67 μM. This was the first report about zirconium complex obtained from nature and ochratoxins isolated from marine environment.<br /> (Copyright © 2012 Elsevier Ltd. All rights reserved.)
