Principle, traits and functions of electrochemical fingerprint of Chinese traditional medicine

In regard to such challenging analysis problems as scientific identification and quality evaluation of Chinese traditional medicine, the electrochemical fingerprint technique of Chinese traditional medicine has been researched. The principle, traits, functions, etc., of the electrochemical fingerprint have detailedly been analyzed and discussed by the B-Z oscillatory system using malonic acid as main dissipation substance, characterized by the fact that different influences of different Chinese traditional medicines on the mechanism of the oscillatory reaction cause different changes of the shape of the potential-time curve of the oscillatory system under the conditions of constant temperature and pressure. An economical, simple and convenient, easy pushing and effective scientific method for distinguishing and evaluating multifarious Chinese traditional medicines has successfully been put forward.
