## Abstract ^3^H‐Ochratoxins A, B, and C were obtained by tritiation of the toxins with tritiated water in acetic acid and platinum at 80° C overnight. The toxins were purified by solvent partition and thin layer chromatography with the recovery yield being 80% and the specific activity being 2.6 –

Ochratoxin A is a mycotoxin produced by Asperqillus and Penici1l.w moulds. The toxin is an amide formed between phenylalanine and the isocoumarin acid ochratoxin a . Ochratoxin A with high specific radioactivity can be obtained, by sub titution of the natural phenylalanine for I4C or %-labelled phe
