Application of solid phase extraction method to extract Azlamptic sleeping pills in urine. The optimal pH value of solid phase extraction of azole and the extraction conditions of solid phase adsorption column were discussed. The recovery rate of azole was higher than 75% The extraction recovery rate of drug-solid phase extraction was more than 70%. The solid phase extraction method and GC / ECD qualitative and quantitative analysis method of midazolam sedative drug in biological samples were established
