摘要: 建立了测定发酵液中喷司他丁含量的反相高效液相色谱-质谱分析方法。采用的色谱条件: 色谱柱为Hypersil ODS2柱(250 mm×4.6 mm, 5 μm);流动相为甲醇/乙腈/10 mmol/L乙酸铵(pH 7.6)(2.5/2.5/95, v/v/v),流速为1.0 mL/min;检测波长为280 nm;柱温为40 ℃;进样量为10 μL。喷司他丁在1.0~100 mg/L范围内有良好的线性关系,相关系数为0.9999。该方法精密度好,稳定性高,能简便、快速、准确地测定发酵液中喷司他丁的含量。

Abstract: A method for the determination of pentostatin in culture broth was established using high performance liquid chromatography-mass spectrometry (HPLC-MS). The chromatographic conditions used were as follows: the analytical column was Hypersil ODS2 (250 mm×4.6 mm, 5 μm); the mobile phase was methanol/acetonitrile/10 mmol/L ammonium acetate (pH 7.6) (2.5/2.5/95, v/v/v) with a flow rate of 1.0 mL/min; the detection wavelength was 280 nm; the injection volume was 10 μL; the temperature was 40 ℃. The linear range of the method for pentostatin was 1.0-100 mg/L (r=0.9999). The method is characterized by simplicity, higher sensitivity and accuracy.
