[Aflatoxins occur naturally in a number of agricultural commodities.] A method is described for the preparation and purification of aflatoxin B1-1-(O-carboxymethyl) oxime from aflatoxin B1. The overall yield was about 73-83%. The new aflatoxin B1 derivative was characterized by mass, UV, IR and NMR spectral analyses, and was nontoxic to 8-day-old chicken embryos when tested at a concentration of 3.48 .mu.g/egg.
