To develop and validate a rapid liquid chromatographic method utilizing a Mycosep multifunctional cleanup column to quantify aflatoxins in various agricultural commodities.
Extracted agricultural samples with an acetonitrile-water (9 + 1) mixture and passed aliquots through a specialized Mycosep multifunctional cleanup column to remove matrix interferences.
Derivatized aflatoxins B1 and G1 into hemiacetals using a water-trifluoroacetic acid-acetic acid solution heated at 65 °C for 8.5 minutes.
Quantified total aflatoxins using isocratic liquid chromatography with fluorescence detection across commodities including corn, nuts, rice, and animal feeds.
Achieved a lower limit of detection below 0.5 ng/g for aflatoxin B1.
Obtained average recoveries exceeding 95% for total aflatoxins (B1, B2, G1, and G2) alongside coefficients of variation below 3%.
