Determination of the content of oxacillin sodium for injection by polarimetry
-
摘要: 目的 建立旋光法测定注射用苯唑西林钠含量的方法。方法 以水为溶剂,运用旋光法对注射用苯唑西林钠进行含量测定。结果 苯唑西林钠浓度在1~10mg/mL范围内与其旋光度呈良好线性关系,回归方程:C=0.391314+5.26150a,r=0.9997,平均回收率102.1%,RSD为1.83%。结论 本法简便易行,结果准确,可作为该原料的质控方法。Abstract: Objective To establish an accurate method for determination of the content of oxacillin sodium for injection. Methods Oxacillin sodium for injection was determinted with as water by polarimetry. Results The standard curve was linear in the range of 1~10 mg/mL. The regression equation was: C = 0.391 314 + 5.261 50a,r = 0.9997. The average recovery rate was 102.1%,RSD
