The present paper gives a survey of the chemical, physical and biological properties of the mycotoxin sterigmatocystin. It must be regarded as toxic to warm-blooded animals and as cancerogenic. It is likely to occur in foods; therefore, its analytical detection is necessary. With reference to known

β¦ Synopsis
To test the suitability of fruit as an appropriate substrate for the formation of the mycotoxin sterigmatocystin, various fruit products were inoculated with a suspension of spores of a toxicogenic strain of Aspergillus versicolor. After incubation at 22 degrees C for 14 days, the fruits and juices overgrown with mould were homogenized with ethyl acetate and subjected to thinlayer chromatography. Sterigmatocystin had been formed on most products, the largest amounts being found in gooseberry preserves (9.4 microgram/g) and in grapes (10 microgram/g). The experiments show that fruit is generally suited as a substrate for the formation of sterigmatocystin; consequently, the latter is likely to occur in the presence of Aspergillus versicolor.

A total of 142 samples of vegetable foods was examined for the occurrence of sterigmatocystin. The samples examined were fruits and vegetables which had spontaneously gone mouldy or begun to rot under natural conditions on the one hand, and organoleptically impeccable fruit juices and maize specimen
