Reversed phase high performance liquid chromatog. was applied to the determinations of aflatoxin M1 in milk and its products. The sample was extracted with chloroform and purified by passing through silica gel solid phase extraction column and aflatoxin M1 was eluted from the solid phase extraction column with a mixed solution of chloroform and acetone (1+1). The eluate was separated by gradient elution with acetonitrile solution of different concentration from ZORBAX SB C18, column and their contents determined by fluorescence detector. Linear relationship between values of peak area and mass concentration of aflatoxin M1 was obtained in the range of 1.0-25 渭g/L-1, with detection limit (3S/N) 0.05 渭g/kg-1. The proposed method was used in the anal. of milk and milk powder for their contents of aflatoxin M1and values of recovery found by standard addition method were in the range of 76.0-80.0% and 76.7-90.8% resp. and values of relative standard deviation’s (n=6) found were less than 7.0%.
