Determination of the content of Huperizini-A in tabellae huperizinz-A by the first-derivative spectrophotometry
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 avera
