Resumen
É descrito um método para determinação das aflatoxinas B1 B2 G1 e G2 por cromatografia líquida de alta resolução. As aflatoxinas foram extraídas, cromatografadas em coluna de fase reversa, e detectadas no ultravioleta a 350 nm. Nos testes efetuados, a recuperação variou de 92 a 106%. ° método foi aplicado em dez amostras de farelo de amendoim e em amendoim em grão. °limite de detecção foi de 2 ppb (/Lg/kg).
