摘 要 目的:建立测定人血清中内源性氢化可的松与可的松含量的方法。方法:采用迪马Diamonsil C18色谱柱(250 mm×4.6mm,5 μm);流动相:乙腈-水-甲醇(51:136:77);流速:1.2ml·min-1;紫外检测波长:245 nm;柱温:30 ℃;进样量:30 μl。结果:氢化可的松在50.0~300.0μg·L-1,可的松在10.0~100.0μg·L-1的浓度范围内线性关系良好。氢化可的松与可的松的方法回收率分别为(101.83±1.19)%和(100.52±5.91)%。92名健康者血清中氢化可的松、可的松的浓度分别为(111.60±27.30)和(18.66±4.44)μg·L-1,其比值为(6.08±1.10)。结论:本法操作简便,灵敏度高,快速可靠,适用于氢化可的松与可的松含量的测定,为研究人体肝脏11β-羟基类固脱氢酶(11β-HSD)的活性及调整激素治疗方案提供有效的分析手段。

ABSTRACT Objective:To establish a HPLC method for determination the contents of cortisol and cortisone in human serum.。Method: The Diamonsil C18 column (250 mm×4.6mm,5 μm )was used and the mobile phase was acetonitrile-water-methanol (51:136:77),and flow rate was 1.2ml·min-1,detected wavelength was at 245 nm,and the column temperature was 30 ℃,the sampling volume was 30 μl。Result:F and E in serum solution were well separated. The linear correlation coefficient ofcortisolcalibration curve was 0.999 4 within the range of 50.0-300 μg·L-1,and the average recovery was(101.83±1.19)% 。The linear correlation coefficient of cortisone calibration curve was 0.997 4 within the rang of 10.0-100 μg·L-1,and the average recovery was(100.52±5.91)%,respectively。The levels of cortisol and cortisone in the serum of 92 healthy volunteers were(111.60±27.3)μg·L-1 and(18.44±4.44)μg·L-1,respectively。 Cortisol/cortisone was 6.08±1.10。Conclusion: The methods are simple,accurate,stable and suitable for measuring human serum glucocorticoid。
