Abstract: A method was developed for the extraction and determination of unconjugated aflatoxins in human urine by high-performance liquid chromatography. The analysis is based on the elimination of lipid-soluble constituents other than unconjugated aflatoxins in urine by light petroleum extraction. The unconjugated aflatoxins were subsequently extracted from the aqueous phase with chloroform-acetone. Chromatography was performed isocratically with a silica column at 40°C. The resolved aflatoxins were detected and identified by ultraviolet and fluorometric detectors. The recoveries of aflatoxins B1and G1added prior to the extraction were 72% and 83%, respectively. This procedure is simple, sensitive and practically useful for epidemiological survey of unconjugated aflatoxins in human urine from areas with a high risk of aflatoxin consumption. © 1983.
