It had been found by Allcroft71 that certain isolated extracts of the milk produced by lactating cattle that had been fed sublethal levels of the aflatoxins, induced the formation of the liver lesions reminiscent of aflatoxicosis72,73. The toxins were isolated and called the milk toxins , which were later redesignated as the aflatoxins 18,74,75). Indeed, it was also demonstrated that the milk toxins were present in the original Aspergillus flavus mold as minor components72. ...

From the screening of 41 microorganisms sfrains, only one Aspergillus flavus ATCC 9170) was able to transform ursolic acid, resulting in fhe formation of ursonic acid (3-oxo-ursolic acid, 103) in low 5tield [81].
