Resumo
Aflatoxinas B" M, e M2 foram completamente separadas por cromatografia líquida de alta resolução em coluna de fase reversa (C18), tendo como fase móvel acetonitrila - água (35 + 65%) a um fluxo de 2,0 ml/min. Os compostos foram detectados por absorção no ultravioleta a 350 nm. Os picos e tempo de retenção tiveram boa reprodutibilidade. A recuperação de afia toxina M, foi de 87,5% e a de M2 foi de 102%. Os limites de detecção para aflatoxina M, e M2 foram 0,2 ppb e 0,1 ppb respectivamente.
