摘要
目的 建立测定氨苄西林、丙磺舒血药浓度的高效液相色谱法。方法 色谱柱:Symmetry Shield^TM RP18柱(5μm,150mm×3.9mm);流动相氨苄西林:0.068mol/L的磷酸二氢钾溶液(pH3.0)-乙腈(92:8,V/V),丙磺舒:水-乙腈-1mol/L的磷酸二氢钾溶液.1mol/L冰醋酸(59.5:39.8:0.62:0.08,V/V,加入0.15%的三乙胺调至pH2.76)。流速均为1.4ml/min;检测波长氨苄西林为210nm,丙磺舒为254nm。结果 氨苄西林的浓度在1.25~40μg/ml范围内线性关系良好(r=0.9999),丙磺舒的浓度在0.625~20μg/ml范围内线性关系良好(r=0.9999)。结论 本法操作简便,灵敏,快速.重现性好,适用于人体药动学研究。
Objective To develop a high performance liquid chromatography (HPLC) method to determine the concentration of ampicillin and probenecid in human plasma. Methods A Symmetry ShieldTM RP18 column (5μm, 150 mm × 3.9 mm)was used. The mobile phases were 0.068 mol/L KH2PO4 (pH 3.0) : acetonitre (92:8 ,V/V) for ampicillin, H2O: acetonitrile: 1 mol/L KH2PO4:1 mol/L acetic acid (59.5: 39.8: 0.62: 0. 062 ,V/V, 0.15% triethylamine added to reach pH 2.76) for probenecid. The detective wavelength were at 254 nm for probenecid and 210 nm for ampicillin. Results The calibration curves obtained were linear in the range of 0.625 - 20 μg/ml ( r = 0. 999 9 ) of probenecid and 1.25 - 40μg/ml of ampicillin. Conclusion This analysis method is simple, sensitive and rapid, suitable for studying pharmacokinetics of ampicillin and probenecid.
