Abstract

目的 建立血清中氯美扎酮定性定量的气相色谱测定法,为临床救治氯美扎酮中毒提供诊断依据.方法 取0.5 ml血清加50g/L氢氧化钠50μl混匀,加乙酸乙酯2.0 ml充分震荡萃取,静置5 min,4000 r/min离心,取上清液,氮气吹干.50μl无水乙醇定容,气相色谱法测定,1.0μl进样.结果 血清中氯美扎酮浓度在5.0~100 μg/ml范围内呈线性,最低检出浓度2.0 μg/ml.回归方程y=962.8x+1543.6,相关系数为0.9995,方法回收率为82.5%~101.3%;相对标准偏差(RS)为:3.5%~4.91%.日内、日间RSD分别为3.18%~4.49%和4.16%~4.95%.结论 该方法操作简便、分析快速,结果准确.为临床治疗疑似氯美扎酮中毒患者的药物定性定量检测,提供了一种简便准确的检测方法。
