title: [Mycotoxins in enzyme preparations. Part II. Method of detection and determination of sterigmatocystin].
abstract: A simple method for the detection and semiquantitative determination of sterigmatocystin in enzyme preparations was described. The method comprises extraction with acetonitrile and a 4% aqueous KCL solution, column chromatographic purification of the crude extracts on silica gel, and two-dimensional thin-layer chromatography. The mean recovery by this method is from 71 to 79%, and the detectability of sterigmatocystin is 20 micrograms/kg.
