  • Title: High pressure liquid chromatographic determination of aflatoxins in spices.
    Author: Awe MJ, Schranz JL.
    Journal: J Assoc Off Anal Chem; 1981 Nov; 64(6):1377-82. PubMed ID: 7309657.
    Abstract:
    High pressure liquid chromatography with fluorescence detection is used to determine aflatoxin in 5 common spices. A 10 micrometer microparticulate silica gel column is used with a dichloromethane-cyclohexane-acetonitrile solvent system to resolve aflatoxins B1, G1, B2, and G2. The fluorescence detector contained a silica gel-packed flowcell. Samples of black, white, and red pepper, ginger, and nutmeg were extracted according to a previously published method. Recoveries from aflatoxin-free samples of white pepper, ginger, and red pepper spiked with 1-50 micrograms aflatoxin/kg ranged from 64 to 92%.
