| Abstract_FL | ABSTRACT:Objective To establish an immunoaffinity chromatography-high performance liquid chromatography (HPLC) fluorescence detector coupled with post-column photochemical derivatization method for determination of the aflatoxin B1, B2, G1, and G2 in food.Methods The sample was tested by HPLC with fluorescence detector after being homogenizer extracted from methanol-water (70:30,V:V), purified by immunoaffinity chromatography column of aggregated aflatoxin, separated by Welch Ultimate?XB-C18 HPLC column, eluted with a mobile phase consisting of methanol and waters (45:55,V:V) and derived from post column photochemical derivative reactor. The content of aflatoxin B1, B2, G1, and G2 in food was measured using peak area external standard method.ResultsThe calibration curves showed a good linearity in each concentration range with correlation coefficient greater than 0.999 within linear range 0.3~50.0 μg/L. The limits of detection (LODs) were 0.15, 0.05, 0.15 and 0.05μg/kg for the aflatoxins B1, B2, G1, and G2 in food, respectively. The recovery rate was within 80.7 %~92.6 % at 3 adding levels with the relative standard deviation (RSDs) of 2.04~3.87%.ConclusionThis method is sensitive, accurate and precise, which is in accordance with technical standards of the aflatoxins detection. It is proper for routine detection of the aflatoxins B1, B2, G1, and G2 in food. |
