摘要
采用一阶导数紫外光谱法中的峰-零法测定石杉碱甲片(双益平)中石杉碱的含量,测定波长为318nm。三组不同量样品的平均回收率为98.25％,平均RSD为2.4％(样品总数n=30)。测定方法简便准确。
A first derivative UV-spectophotometric method was successfully used by peak-zero method for the determination of Huperzini-A in tabellae huperizinz- A, the wave length of detenniniation was 318nm.The average recovery of three groups was 98.25% ,the average RSD was 2.4% (n =30).The method is simple and accurate.
