Abstract The experiment design of the physical chemistry experiment “B-Z oscillating electrochemical fingerprint of phloridzin” in medical or pharmaceutical universities was completed. And the design mentality was briefly introduced. The standard experimental operation method and data processing method were established. The obtained B-Z oscillating electrochemical fingerprint was stable and clear,with good reproducibility and strong specificity. The characteristic parameters obtained by processing can be used for qualitative and quantitative analysis. The influence of temperature and phloridzin concentration on B-Z oscillation was also studied. The results showed that the experimental data at different temperatures fitted Arrhenius equation well. When phloridzin concentration was lower than 0.4 mmol/L,quantitative analysis could be carried out by this operation. When phloridzin concentration was higher than 0.4 mmol/L,oscillation stop phenomenon could be observed.
