Stability of aflatoxin B 1 in aqueous solutions at different temperatures and p H values was studied by thin‐layer chromatography and fluorodensitometric measurements. The rate of deterioration was found to be increased with increasing temperature and also by changing p H from neutral to alkaline or acid. In acidic buffers the aflatoxin was converted to a new fluorescent product which has much lower R f value than aflatoxin B 1 itself when chromatographed on silica gel thin‐layer plates developed with chloroform‐methanol(99:l, v / v ). The UV absorption spectrum of this decomposition product has been determined.
