Abstract: Aprocedure for detecting β-blockers was establ ished.Five β-blockers were administrated to rats. The rats' metabolic urine tqamples were hydrolysed with β-glucuronidase,extracted by Sep-Pak C18 columns,and analyzed by GC/MS.Their metabolites were identified by mass spectra and metabolic theories.The recoveries of the drugs were all over 75%.The hydrolysed metliods were compared and the mass fragmentation mechanism was discussed.

Key words: β-blocker, Metabolite, GC/MS
