because the metabolites aflatoxin m1 , aflatoxin p1 , aflatoxin q1 , sterigmatocystin , and o-methylsterigmatocystin have the same molecular conversion site , we investigated the chromatographic and spectroscopic properties of hemiacetals of these compounds to assist in confirming aflatoxins and sterigmatocystins in human urine .
