摘要:

目的 建立高效液相色谱-质谱联用法测定人血浆中氨基葡萄糖的浓度。方法 选用Agilent TC-C18色谱柱,以乙腈-0.01%氨水为流动相,采用梯度洗脱进行分离,样本先用5%磺基水杨酸沉淀,上清液用二氯甲烷液-液萃取后进样,选用3200QTRAP型质谱仪的多重反应监测扫描方式进行检测。结果 氨基葡萄糖线性范围为20.0~2 000.0 ng/mL,定量下限为20.0 ng/mL。准确度与精密度结果显示方法日间、日内变异均小于15%,相对偏差为-0.30%~1.69%,低、中、高3个浓度提取回收率为93.59%~106.27%,稳定性较好。结论 该方法快速、灵敏、专属性强、重现性高,可用于人体氨基葡萄糖血药浓度的监测,及其制剂的人体药代动力学研究。

Abstract:

Objective To develop a LC-MS/MS method for the determination of glucosamine in human plasma. MethodsGlucosamine was extracted with dichloromethane from the supernatant after protein precipitation with 5% sulfosalicylic acid and separated by gradient elution on an Agilent TC-C18 column using acetonitrile -0.01% ammonia water as mobile phase. Detection was carried out by multiple reaction monitoring (MRM) on a 3200QTRAP LC-MS/MS system. Results The assay was linear over the range 20.0~2 000.0 ng/mL with a lower limit of quantitation of 20.0 ng/mL. The intra-and inter-day precision were less than 15%. The relative deviation was in the range -0.30%~1.69%. The recovery of glucosamine was in the range of 93.59%~106.27%.Conclusion The method is a rapid, sensitive, selective and reliable one for the determination of glucosamine in human plasma. The assay could be applied to a pharmacokinetic study in healthy volunteers.
