摘要
目的:建立左乙拉西坦注射液中有关物质的HPLC测定方法,并进行方法学验证。方法:Dikma Platisil ODS色谱柱(柱长250 mm,内径4.6 mm,粒径5μm),以质量分数0.1%磷酸水溶液为流动相A,乙腈为流动相B,梯度洗脱,紫外检测器检测,流速1.0 mL/min,检测波长205 nm,柱温30℃,进样量20μL。结果:左乙拉西坦与杂质分离度好;方法学验证结果均符合要求。结论:本方法专属性强,灵敏度高,耐用性好,可用于左乙拉西坦注射液有关物质的测定。
Purpose:An HPLC method for the determination of related substances in levetiracetam injection was established and the method was verified.Methods:Dikma Platisil ODS column(length 250 mm,diameter 4.6 mm,particle size 5μm),with 0.1%phosphoric acid aqueous solution as mobile phase A and acetonitrile as mobile phase B,gradient elution,Ultraviolet detector detection,the flow rate was 1.0 mL/min,the detection wavelength was 205 nm,the column temperature was 30℃,and the sample size was 20μL.Result:Levetiracetam is well separated from impurities.The results of methodology verification meet the requirements.Conclusion:The HPLC method has strong specificity,high sensitivity and good durability,and can be used for the determination of related substances in levetiracetam injection.
