| The optimization of the thin layer chromatography (TLC) method to determine aflatoxins in feedstuffs and the evaluation of their occurrence in feedstuffs for milk-yielding does in the state of Bahia were studied. Eighty feedstuff samples were collected from five farms, located in the Recôncavo Baiano, from November 2000 to August 2002. The samples were analyzed using TLC modified method. In this study, the detection and quantification limits were 5 and 8m g/kg, respectively. The percentage of average recoveries obtained for AFB1, AFB2, AFG1, and AFG2 were 81.0; 97.2; 89.3; and 90.3%, respectively; and the coefficient of variation ranged from 0.83 to 4.1%. The results revealed that the optimization of TLC methodology is efficient to analyze aflatoxins in... |
