紫外二阶导数光谱标准加入法测定中药复方制剂中合成鱼腥草素含量

Determination of Synthetic Decanoyl Acetaldehyde in Compound Chinese Medicines by Standard Addition Method of UV Second Order Derivative Spetrum

  • 摘要: 将紫外二阶导数光谱与标准加入法相结合应用于药物分析,定量测定中药复方制剂中合成鱼腥草素的含量。根据比尔定律推导出标准加入体系的含量计算公式为X_i=X_i×C_i/K-C_i×V_i。方法精密度CV1.3%;平均回收率99.40%,回收率CV1.9%。本法消除了中药复方制剂中样品基质的干扰,结果准确可靠。
