Abstract A solvent mixture of acetonitrile-benzene (1+9) was investigated as a means to eliminate instability of aflatoxin M1 standard solutions prepared with chloroform. Solutions (10.0 μg/mL) were prepared and sealed in glass ampules that were opened as needed for absorbance measurements on the individual solutions over a 13-month period. A coefficient of variation of 0.69& for the absorbance readings indicated that the solutions were stable. In addition, numerous powdered milk extracts containing aflatoxin M1 were dissolved in both chloroform and acetonitrile-benzene (1+9), and the solutions were spotted on TLC plates and developed. Densitometric measurement of the developed zones showed no differences due to the spotting solvent. The molar extinction coefficient was determined in acetonitrilebenzene (1+9) on 4 different M1 solutions from 2 separate crystalline aflatoxin M1 preparations; the value was 18,815 ± 24.
