Abstract: The copper plate coated with PVCmembrane (containning berberine-tetraphenylborate) was used as the indicator electrode, while berberine was titrated with sodium tetraphenylborate by oscillo-potentiometric titration. This method is precise, audio-visual, simple and convenient and can be used in the determination of other drugs.

Key words: Oscillo-potentiometric titration, Sodium tetraphenylborate, Berberine
