Objective: To establish the electrochemistry fingerprint of Rhizoma Pinelliae. Method: H+-Mn2+-CH3COCH3-BrO-3chemical oscillation system was used with Chinese herbal medicine as reaction substrate to get the electrochemistry fingerprint of Chinese herbal medicine by recording the electrochemical potential of oscillation system over time using electrochemical workstation. Result: Rhizoma Pinelliae and Rhizoma Typhonii had different characteristics and the difference was significant. Conclusion: The method is simple and convenient and can be used to distinguish Rhizoma Pinelliae.
