| Abstract: | This paper developed a new titration method for the determination of zinc in zinc glycyrrhizate.The end point of this method was indicated by the change in the oscillopolarogram of zinc,The established method was simple and rapid compared with the official one and was successfully employed to the determinzation of zinc in zinc glycyrrhizate and its capsule preparation. |
