        摘   要  目的:建立测定人血浆中伏立康唑浓度的方法。方法:血浆经乙腈沉淀蛋白后,以利鲁唑为内标,采用高效液相色谱
       (HPLC)法测定其中伏立康唑的血药浓度。色谱柱为 Agilent Zorbax Eclipse Plus C18,流动相为乙腈-0.01 mol/L 磷酸二氢钾溶液
       (38 ∶ 62,V/V),流速为1.0 mL/min,柱温为40 ℃,检测波长为255 nm,进样量为20 μL。同时将该方法应用于10例使用伏立康唑患
        者的血药浓度测定。结果:伏立康唑检测质量浓度的线性范围为0.2~20.0 μg/mL(r=0.999 6),定量下限为0.2 μg/mL,日内、日间
        RSD均小于7%(n=6或n=18),准确度平均值为98.59%~106.18%,提取回收率平均值为86.77%~89.86%(RSD<4%,n=6),
        稳定性试验实测结果与理论值的偏差在±15%内。10例患者伏立康唑的血药浓度为0.34~5.04 μg/mL。结论:本研究成功建立
        了快速、高效测定人血浆中伏立康唑浓度的HPLC法。

        ABSTRACT    OBJECTIVE:To establish the method for the determination of voriconazole concentration in human plasma.
        METHODS:After protein precipitation with acetonitrile,using riluzole as internal standard,plasma concentration of voriconazole
        were determined by HPLC method. The determination was performed on Agilent Zorbax Eclipse Plus C18 column with mobile phase
        consisted of acetonitrile-0.01 mol/L monopotassium phosphate solution(38 ∶ 62,V/V)at the flow rate of 1.0 mL/min. The column
        temperature was maintained at 40 ℃,and the detection wavelength was 255 nm. The sample size was 20 μL. Meanwhile,the
        method was applied to determine plasma concentration of voriconazole in 10 patients receiving voriconazole. RESULTS:The liner
        range of voriconazole was 0.2-20.0 μg/mL(r=0.999 6). The lower limit of quantitation was 0.2 μg/mL. RSDs of intra-day and
        inter-day were both lower than 7%(n=6 or n=18). Average accuracies were 98.59%-106.18%. Average extraction recoveries
        were 86.77%-89.86%(RSD<4%,n=6),and the deviations of measured results and theoretical values of stability tests were within
        ±15%. The plasma concentrations of voriconazole in 10 patients were 0.34-5.04 μg/mL. CONCLUSIONS:The study successfully
        establish a rapid and efficient HPLC method for the determination of voriconazole in human plasma.
