ABSTRACT

OBJECTIVE@#Screen seventeen benzodizepines and their metabolitesin urine by GC/ECD and GC/MS.@*METHODS@#They were GC (GC/ECD, GC/MS) assay of benzodizepines and GC (GC/ECD, GC/MS) assay of benzophenones of acid-hydrolytic products of 1,4-benzodizepines.@*RESULTS@#The methods were simple and sensitive. The recoverys were 60% to 90% of most benzodizepines, linear calibration curves were 20 ng/ml-200 ng/ml (r > 0.99), and detection limits were 0.5 ng/ml-10 ng/ml.@*CONCLUSION@#They methods were evaluated with human urine samples.

ABSTRACT

Se describe un método de determinación de 1,4-benzodiazepinas en orina por cromatografía líquida de alta eficacia, luego de la hidrólisis ácida a sus correspondientes benzofenonas. En el presente trabajo se logró optimizar el rendimiento en benzofenonas variando las condiciones de hidrólisis y empleando diferentes pH y solventes de extracción. La separación de las benzofenonas se llevó a cabo con una columna de fase reversa de octadecilsilano, en condiciones isocráticas y detección UV a 254 nm. La sensibilidad del método es de 250 ng de benzodiazepina por ml de orina
