摘　　要：目的:建立尿中甲基苯丙胺的气相色谱/质谱(GC/MS)定性,定量分析方法,比较液-液提取和固相萃取两种方法。结果:尿中甲基苯丙胺液-液提取的回收率约82.3%;固相萃取方法回收率为91.3%。结论:尿中甲基苯丙胺提取采用固相萃取的方法比液-液提取效果好,方法简便、灵敏,适用于甲基苯丙胺中毒与滥用案件的定性定量分析,满足实际办案的需要。Objective： To establish methamphetamine in urine by gas chromatography / mass spectrometry （GC / MS） qualitative and quantitative analysis, comparing the liquid - liquid extraction and solid phase extraction methods. Results： Methamphetamine in urine liquid - liquid extraction recoveries of approximately 82.3 %; solid phase extraction method recovery was 91.3 %. Conclusion： Methamphetamine in urine extraction method using solid phase extraction ratio of liquid - liquid extraction, simple method, sensitive, applicable to cases of abuse of methamphetamine intoxication with qualitative and quantitative analysis, to meet the needs of the actual handling.
