Abstract
Olympic Committee (IOC) prohibits the use of cyclofenil for male. To prove whether cyclofenil product was taken or not, the analytical method in urine using GC/MS was established. The extraction recoveries of cyclofenil and its metabolites were higher in the range of pH 5-9. Because the parent drug (cyclofenil) was not excreted in urine, metabolites were detected and theses were used as a criteria of cyclofenil dose. Therefore the metabolites were hydrolyzed, extracted at pH 9.6, derivatized with MSTFA and analyzed by GC/MS.
