| Abstract: | Aflatoxin is one of main carcinogens and its acute toxicity is strong. In this study, aflatoxins in food and feed were determined by HPLC with post-column photochemical derivatization, and the effects of photochemical derivatization on aflatoxin fluorescence were investigated. The results show that via post-column photochemical derivatization, the detection sensitivity of four kinds of aflatoxin are high and the detection limit is as low as 3.25pg. |
