本文报道阿片类药物依赖性患者尿标本中吗啡的薄层色谱检定法。薄层板为硅胶GF-254,检测方法用紫外分析灯和Dragendorff试剂显色。应用本法检测尿中吗啡的检测限为2μg。特异性好,一些常见合并用药不干扰吗啡测定。用本法检测72例阿片类药物依赖性患者约200份尿标本,结果表明,停用毒品后24~48小时可检出其中的吗啡。本法所得结果准确,操作简便,所需仪器条件低,适合大面积应用于阿片类药物滥用的流行学调查和该类患者的诊断与治疗过程中的监测。

A rapid sensitive method has been developed for the determination of the concentration of morphine in drug addicts' urine by using GC/MS combined with Selected Ion Monitoring (SIM) technique. The peak area ratio of morphine to dihydrocodeine(internal standard) is proportional to the concentration of morphine from 10 ng/mL to 1000 ng/mL. The recovery and detection limit are 96. 6±1. 8(n = 4) and 0. 5 ng. The method has been used to determine the concentration of drug addicts who were being treated in a hospital....

A capillary gas chromatography-mass spectroscopy procedure for simultaneous quantitative determination of codeine and morphinein the urinc of opiates addicts is described.An internal standard,nalorphine,was added to the urine samples.The samples were hydrolyzed with acidic,condition in boilling water bath and extracted with organic solvent.The extracted codeine,morphine and naloerphine were derivated to the acetylated compounds.Then the acetylated compounds were separated by,capillary gas chromatography and identified mass spectrometrically by selected ion monitoring(SIM).Quantitative determination was carried out by SIM using internal standard.The derivatives were stable at room temperature for 48 hour.Excellent linearity was obtained over a concentration range of 20 to 600μg/1 and 20 to 800μg/1 for codeine and morphine,respectively.The detected limitation for both drugs was 2μg/1 at a peak-to-noise ratio of 5:1.The precision of day-to-day(CV%)for codeine was 3.12(50μg/1)and 1.64(200μg/1).That for morphine was 3.12(50μg/1)and 2.51(200μg/1).About 200 samples were determined by the procedure,The morphine in the urine of the addicts stopped taking drugs for 10 days canbe measured.

本文报告阿片类药物依赖性患者尿标本中同时测定吗啡和可待因的气相色谱-质谱联用法(GC-MS)的方法学研究和部分病例尿标本的测定结果。尿标本(或含吗啡和可待因的尿标准溶液)加丙烯吗啡做为内标物,经酸性条件下水解后用有机溶剂提取纯化。提取物在无水吡啶中用醋酐进行乙酰化,乙酰化衍生物进样分析。定量方法采用选择离子检测法(SIM)。可待因、吗啡和内标物丙烯吗啡的保留时间分别为1.74,2.34和3.23min,选择三者的基峰341,327和353做为SIM定量的离子。可待因和吗啡的标准曲线线性范围分别为20-600μg/1和20-800μg/1。方法检测限为2μg/1,该浓度下两种药物的信/噪比为5:1。可待因和吗啡高,低浓度的精密度均良好,50和200μg/1可待因的日间变异系数(CV%)分别为3.12和1.64;相同浓度吗啡的日间变异分别为3.12和2.51。衍生化产物室温下48h内稳定。应用本法对阿片类药物依赖性患者近200份尿标本进行测定结果显示,该法可定量测得患者停用毒品后10d尿中的吗啡。
