摘 要:建立高效液相色譜-二極管陣列檢測器法測定青霉素亞砜酯的含量。采用Agilent Eclipse Plus C18(3.0 mm×100 mm,3.5 μm)色譜柱;柱溫30 ℃;以25 mmol·L-1的醋酸銨水溶液(A)-乙腈(B)為流動(dòng)相進(jìn)行梯度洗脫;流速為0.5 mL·min-1;檢測波長(cháng)267 nm。青霉素亞砜酯在0.01~0.80 mg·mL-1(R2=0.999 9)范圍內線(xiàn)性較好,精密度RSD為0.15%。方法操作簡(jiǎn)單,結果準確,特異性強,穩定性好,適用于青霉素亞砜酯的含量測定。

Abstract:A method was established for determination of penicillin sulfoxide ester by high performance liquid chromatography coupling with photodiode array detector. In this method Agilent Eclipse Plus C18(3.0×100 mm,3.5 μm) column was used and the temperature was set at 30 ℃. Gradient elution was performed with 25 mmol·L-1 ammonium acetate aqueous solution and acetonitrile as mobile phase. The flow rate was 0.5 mL·min-1 and the detection wavelength was 267 nm. The calibration curves of penicillin sulfoxide ester was linear in the range of 0.01~0.8 mg·mL-1(R2=0.999 9), and the RSD was 0.15%. This method is simple, accurate, highly specific and good stability, thus can be used for the determination penicillin sulfoxide ester.
Key words:penicillin sulfoxide ester; HPLC; DAD; content determination
