| 摘要: |
| 目的 建立高效液相色谱法测定索拉非尼含量，并探索大鼠血浆中索拉非尼浓度的测定方法。方法 采用Eclipse XDB-C18色谱柱(150 mm×4.6 mm，5 μm)；流动相：0.05%甲酸和0.05%三乙胺的水溶液-乙腈(35∶65)；流速：1.0 mL·min-1；柱温：30 ℃；检测波长：265 nm。结果 索拉非尼浓度在0.4~12 μg·mL-1内线性关系良好，r=0.999 9；加样回收率为100.8%，RSD为1.470%。大鼠按65 mg·kg-1灌胃给药，给药2.5 h后，其血浆中索拉非尼的药物浓度为2.830 μg·mL-1。结论 本法可用于甲苯磺酸索拉非尼片中药物含量的测定，方法简单、灵敏，同时可检测大鼠血浆中索拉非尼的浓度。 |

| Abstract: |
| OBJECTIVE To establish a high-performance liquid chromatography method for determination of sorafenib, explore a method of measuring the sorafenib concentration in rat blood plasma. METHODS Agilent Eclipse XDB-C18 column (150 mm×4.6 mm, 5 μm) was used. The mobile phase was 35%(0.05% formic acid and 0.05% triethylamine) in aqueous solution and 65% acetonitrile while the flow rate was 1.0 mL·min-1. The column temperature was 30 ℃. The detection wavelength was 265 nm. RESULTS The standard curve of sorafenib concentration was linear in the range of 0.4-12 μg·mL-1(r=0.999 9). The average recovery rate of the method was 100.8%, RSD was 1.470%. The rat was treated by gavage with sorafenib at the dosage of 65 mg·kg-1. The sorafenib concentration in rat blood plasm was 2.830 μg·mL-1. CONCLUSION The method is suitable for the determination of sorafenib. It is practicable, simple, sensitive, and can be used to measure the sorafenib concentration in rat blood plasma. |
