Abstract
Objective To develop an analysis method for determining drugs from blood.Methods Methadone, cocaine, thebaine and heroin in blood were extracted by accelerated solvent extraction(ASE) and analyzed with GC/MS.Results The recoveries of four drugs were ranged from 87.8% to 97.5%. A good linear relationship was obtained at the concentration range of 0.4μg/mL ~4.0μg/mL.Conclusion The method has high recovery, good repeatability and easy to operation. It can be used to the casework.

A method for the determination of 10 mixed drugs of abuse in blood was developed by gas chromatography-mass spectrometry(GC/MS) coupled with accelerated solvent extraction(ASE). The target analytes were extraceted with V (ethyl acetate)∶ V (cyclohexane)=1:1 by accelerated solvent extraction,and cleaned by auto gel permeation chromatography(GPC). The qualitative and quantitative analysis were carried out by GC/MS. The total ion chromatogram and selected ion chromatogram were obtained. The calibration of mdma, phenacetinum, ketamine, ramadol, cocaine, thebaine, papaverine, narcotine have a good linear relationship in the range of 1.2—7.2 mg•L -1 , meperidine has a good linear relationship in the range of 2.4—7.2 mg•L -1 , and herion has a good linear relationship in the range of 1.2—6 mg•L -1 . The linearity correlation cofficients of 10 mixed drugs of abuse are between 0.993 and 0.997. The average recoveries are 91%—97% with relative standard deviations of 2%—9.5%.
