摘　　要：建立高效液相色谱法测定胞磷胆碱钠与10%葡萄糖配伍注射液中5-羟甲基糠醛含量,并将其用于配伍溶液在不同输液器具中的稳定性研究。胞磷胆碱钠与10%葡萄糖配伍注射液,采用Thermo Scientific BDS HypersilTM C18色谱柱(250 mm×4 mm,5μm)分离,柱温为40℃,以10 mmol/mL四丁基氢氧化铵-15 mmol/mL磷酸氢二钠溶液(用20%磷酸调pH值至6.0)-甲醇作为流动相进行梯度洗脱。进样体积为15μL,检测波长为284 nm。5-羟甲基糠醛在0.02~54.09μg/mL质量浓度范围内线性关系良好(r=0.9999)。方法定量限为0.02μg/mL,检出限为0.005μg/mL。样品加标回收率为99.5~100.6%,测定结果的相对标准偏差(RSD)为0.66%。配伍溶液在聚烯烃热塑弹性体(TPE)、聚氯乙烯(PVC)材质输液器具中8 h内,5-羟甲基糠醛质量分数的相对偏差均小于0.6%(n=6),胞磷胆碱钠质量分数相对偏差均小于2.8%。该方法操作简单、灵敏度高,适用于5-羟甲基糠醛含量及其配伍溶液稳定性研究。A high performance liquid chromatography method for the determination of 5-hydroxymethylfurfural in citicoline sodium and 10%glucose combined injection was established and used to study the stability of the compatible solution in different infusion devices.The samples were citicoline sodium and 10%glucose combined injection and separated on Thermo Scientific BDS HypersilTMC18 column(250 mm×4 mm,5μm)at a column temperature of 40℃.Gradient elution was performed with 10 mmol/mL tetrabutylammonium hydroxide-15 mmol/mL disodium hydrogen phosphate solution(pH adjusted to 6.0 with 20%phosphoric acid)-methanol as the mobile phase.The sample volume was 15μL and the detection wavelength was 284 nm.The linear relationship of 5-hydroxymethylfurfural was good in the concentration range of 0.02μg/mL to 54.09μg/mL(r=0.9999).The limit of quantification was 0.02μg/mL and the limit of detection was 0.005μg/mL.Recovery rate of samples were 99.5%-100.6%,and the relative standard deviation(RSD)of the measurement results was 0.66%.The compatible injection was in the infusion devices made of polyolefin thermoplastic elastomer(TPE)or polyvinyl chloride(PVC)for 8 h,the relative deviation of 5-hydroxymethylfurfural mass fraction were all less than 0.6%(n=6).The relative deviation of citicoline sodium mass fraction were all less than 2.8%.The established method is simple and sensitive,and is suitable for the study of 5-hydroxymethylfurfural content and the stability of its compatible solution.
