【摘要】:目的:建立并验证超高效液相色谱法(UPLC)测定人血浆中阿司匹林(ASP)和水杨酸(SA)的浓度,并应用于临床ASP和SA血药浓度的测定。方法:色谱柱为ACQUITYUPLC~汶BEH C_(18)(2.1 mm×100 mm,1.7μm),流动相为含0.05%三氟乙酸(TFA)的超纯水和乙腈(78%∶22%),流速0.5 mL·min~(-1),柱温30℃,进样器4℃,检测波长304 nm和277 nm,内标为替硝唑。结果:ASP和SA分别在0.4~100μg·mL~(-1)和0.2~50μg·mL~(-1)线性关系良好(r~20.999);ASP和SA的日内、日间准确度和精密度均15%。结论:本研究建立了一个准确、灵敏且稳定的UPLC法测定ASP和SA血药浓度的方法,可应用于临床ASP和SA血药浓度的测定和药动学研究,指导临床合理用药。
[Abstract]:Objective: to establish and verify the determination of aspirin (ASP) and salicylic acid (SA) in human plasma by ultra-high performance liquid chromatography (UPLC). Methods: the chromatographic column was ACQUITYUPLC- Phenbeh C18 (2.1 mm 脳 100mm ~ 1.7 渭 m),). The mobile phase consisted of ultrapure water and acetonitrile (78: 22%) containing 0.05% trifluoroacetic acid (TFA). The flow rate was 0.5 mL / min ~ (-1). The column temperature was 30 鈩,
