    Determination of Etoposide Injection by First Order Derivative Spectrophotometry

      摘要
    • 摘要: 用一阶导数光谱法测定足叶乙甙注射液的含量。取297nm波谷处振幅绝对值作为定量信息。线性范围32—130ug/ml,相关系数r==0.9999,回收率100.3%,RSD为0.21%。方法简便、快速、准确。

       

      Abstract: The content of etoposide injection was determined by first order derivative spectrophotometry. The absolute value of valley amplitude at 297nm was used for thequantitativedetermination. The repression equation is D = 0. 00,061C + 0.00178C (R = 0. 9999, 32
