[Mycotoxins in enzymatic preparations. 1. Method for the detection and determination of aflatoxins].
A simple method for detection and semiquantitative determination of aflatoxins B1, B2, G1 and G2 in enzymatic preparations is described. The method is based on extraction with a mixture of acetone with water, purification of extracts with lead acetate and on a column with aluminum oxide. The concentrated extracts were analysed by means of two-direction thin-layer chromatography. The mean recovery by this method was from 57 to 78% depending on the type of aflatoxin. The detection limit by this method was about 1 mcg/kg.
