摘要: 建立超高效液相色谱-串联质谱法同时检测中成药和保健食品中非法添加的7种治疗高尿酸血症类药物的方法。色谱柱为ACQUITY UPLC® BEH C18(2.1 mm×100 mm, 1.7 μm), 以0.2%甲酸水溶液-乙腈(流速为 0.3 mL/min)为流动相梯度洗脱;质谱采用电喷雾离子源(ESI), 正离子多反应监测(MRM)模式进行定性定量分析。结果表明, 7种治疗高尿酸血症类药物在相应的质量浓度范围内线性关系良好, 相关系数均大于0. 995, 在低、中、高3个加标水平下的平均回收率为95.49%~104.87%, RSD为1.40%~3.44%, 检出限为0.01~0.30 μg/kg, 定量限为 0.04~1.00 μg/kg, 6批样品中有1批样品检出了非法添加的化学物质。该方法前处理简单, 灵敏度高, 结果准确, 适用于中成药和保健食品中7种治疗高尿酸血症类药物的同时快速定性定量分析。

Abstract: To establish a method for simultaneous detection of 7 hyperuricemia drugs for treatment illegally added to Chinese patent medicines and health foods by UPLC-MS/MS.The samples were extracted from samples with mobile phase, the column was a ACQUITY UPLC® BEH C18(2.1 mm×100 mm, 1.7 μm), a gradient elution with the mobile phase of 0.2% formic acid aqueous solution and acetonitrile solution at a flow rate of 0.3 mL/min. The compounds were detected by electrospray ion source in positive mode with multiple reaction monitoring (MRM) mode.The results showed that all the 7 hyperuricemia drugs for treatment with showed good linearity in their reasonable ranges , and the correlation coefficients were greater than 0.995.The average recoveries of low, medium and high concentrations ranged between 95.49% and 104.87%, and the relative standard deviations were 1.40%~3.44%. The LODs were 0.01~0.30 μg/kg and LOQs were 0.04~1.00 μg/kg.Illegal added chemical drugs were found in 1 of the 6 tested practical samples. With the advantages of simple pre-processed, high sensitivity and accurate results, the method can be used in determination of 7 hyperuricemia drugs for treatment in Chinese patent medicine and health foods.
