目的:建立凝胶色谱法(SEC)测定苯唑西林钠片聚合物。方法:采用依利特色谱柱(填料:Sephadex G-10;尺寸:10.0mm×300mm);流动相A为pH7.0的0.01mol·mL-1磷酸盐缓冲液[0.01mol·mL-1磷酸氢二钠溶液-0.01mol·mL-1磷酸二氢钠溶液(61:39)],流动相B为超纯水;流速1.0mL·min-1;检测波长为254nm;进样量为200μL;以苯唑西林对照品进行测定,按外标法定量。结果:苯唑西林的线性范围1.8051μg·mL-1~18.0511μg·mL-1(r=1.0000),定量限为1×10-3mg·mL-1,重复性良好(RSD为0.24%,n=6);供试品测定的线性范围为1.1252mg·mL-1~11.4653 mg·mL-1(r=0.9997),重复性良好(RSD为2.17%, n=5)。结论:该方法能够较好地分离苯唑西林钠和聚合物,可用于苯唑西林钠片聚合物的检验。

Objective:To establish a size exclusion chromatography (SEC) method for the determination of the polymers in oxacili-in sodium tables. Methods:A Sephadex G-10 gelcolumn (10.0mm×300mm) was used.The mobile phase A was 0.01mol·mL-1 phos-phate buffer solution (pH=7.0), and B was water.The flow rate was 1.0mL·min-1, the detection wavelength was at 254nm, the injection volume was 200μL and the concentration of polymers was quantified by external standard method. Oxacllin was used as substitute ref-erence substance. Results:For HPSEC method, the calibration curves were linera in the range of 1.8051μg·mL-1-18.0511μg·mL-1for oxillin(r=1.0000), and the limit of quantitation was 1×10-3mg·mL-1,The RSD for replicate injection of reference solution was 0.24%(n=5), and the calibratin curves were linear in the range of 1.1252mg·mL-1~11.4653 mg·mL-1 for oxacillin (r=0.9997), and the repeat-ability for 5 measurement results was 2.17%(n=5). Conclusition:This method can be used in separating the polymers from oxacillin preferably, and is suitable for controlling the quality of this drug.
