Objective:
To investigate the kinetic processes of direct electrooxidation for both matrine and sophoridine in a physiological medium.
Method:
Their direct electrooxidative behaviors and the parameters of electrochemical kinetics were obtained by cyclic voltammetry (CV), bulk electrolysis with coulometry, chronocoulometry (CC), chronoamperometry (CA).
Result And Conclusion:
The electrochemical experimental results show that the two totally irreversible oxidation peaks in the region of 0.3-1.2 V vs SCE for both MT and SR were observed, and the electrode reactions processes were diffusion-controlled. Their electron transfer number n and electron transfer coefficient alpha were obtained by CV and electrolysis with coulometry. The diffusion coefficient D and rate constant kf were also calculated by CC and CA.
