  • Title: High performance liquid chromatographic determination of aflatoxicol in milk, blood, and liver.
    Author: Trucksess MW, Stoloff L.
    Journal: J Assoc Off Anal Chem; 1981 Sep; 64(5):1083-7. PubMed ID: 7287604.
    Abstract:
    Samples of milk were extracted with chloroform, the extract was transferred to methanol, and residual interferences were removed by liquid-liquid partition against hexane and by silica gel column chromatography. Aflatoxicol (AFL) in the purified extract was resolved on a mu Bondapak C18 column, using water - methanol - acetonitrile - tetrahydrofuran (70 + 15 + 20 + 3) as the mobile phase, and measured with a fluorescence detector (excitation 325-385 nm, emission greater than 408 nm). Recoveries of AFL added to samples of whole pasteurized milk at levels ranging from 0.025 to 0.10 ng/mL averaged 92% (range 78-100%). The method for AFL has also been applied to the analysis of raw milk, whole beef blood, and beef liver, with recoveries of 70-88%.
