Abstract: 目的建立用柱切换HPLC技术分析尿中吗啡和06-单乙酰吗啡的方法.方法尿样用硼砂缓冲液(pH9.2)稀释后进入预处理柱(YWG-C18,33mm×5.0mm,10μm),用H2O洗去杂质,再用CH3OH:H2O(60:40)将被分析组分洗脱进入分析柱(Lichrospher(R)100CN,125mm×4.0mm,5μm),分析流动相为CH3OH:磷酸盐缓冲液(pH6.86)=22:78.紫外检测器波长为286nm.结果尿中吗啡和06--单乙酰吗啡的线性范围分别为50~1 600n/ml和100~1 600n/ml.吗啡和O6--单乙酰吗啡的精密度均小于4%.吗啡和O6-单乙酰吗啡的检测限均为40n/ml.结论用CSHPLC测定尿中吗啡和O6-单乙酰吗啡,方法准确、灵敏、快速、简便.
