Determining method and conditional factors of electrochemical fingerprint of Chinese traditional medicine

摘要

The thermodynamic systems and kinetic model suitable for the electrochemical token of the component throng in Chinese traditional medicines have been analyzed. It has been indicated that the damp oscillatory reactions in the non-equilibrium close system and open system without the supplement of dissipative substance have important significance for the throng token and analysis of chemical components in Chinese traditional medicines. Various factors influencing the electrochemical fingerprint, such as reactant species and their concentrations, electrode types, temperature, stir rate, the kind, dosage and granularity of Chinese traditional medicines, have amply been researched by the B-Z oscillatory reaction which used malonic acid as a main dissipative substance. In addition, the quantitative information about the chemical components in Chinese traditional medicines has been discussed in detail. The method and its conditions for determining the electrochemical fingerprint used in scientifically distinguishing and evaluating Chinese traditional medicines have successfully been put forward.
