ABSTRACT
Objective To establish a LC-MS/MS assay for simultaneous determination of 25 psychotropic drugs in human blood and apply the method to analyze the relationship between(driving under the inference of drugs, DUID)and traffic violations. Methods Acetonitrile was added to the sample for precipitating the protein, the mixture was centrifuged for 10min at 4℃ , 14000r/min, the supernatant was filtered, and then the filtrate was analyzed with LC-MS/MS. The separation was performed on C18 chromatography column (50mm×3.0mm, 2.6μm), the mobile phase was consisted of 0.1% formic acid (phase A), acetonitrilemethanol=11 (phase B) with gradient elution. Results The calibration curves for 25 psychotropic drugs were linear over the ranges of 0.05~20ng/mL, R=0.9944~0.9996, the assay recoveries were 83.0%~99.7%, the method recoveries were 80.2%~97.4%, the intraday and interday precious were 1.6%~14% and 3.1%~14% respectively. The method was applied to analyze 3140 human samples stored by Center of Forensic Sciences of Hangzhou. Conclusion The method is sensitive and accurate for fast detection of 25 psychotropic drugs in human blood.
