Abstract

Electrochemical oscillation reflects the overall characteristics of the system under test in terms of redox activity. It has proven to be advantageous in analyzing and processing complex components of herbal systems, such as polysaccharides and proteins. Therefore, it is widely used in the quantitative or qualitative tests of traditional Chinese medicines (TCMs) for identification and quality control. Electrochemical oscillation has several advantages such as high sensitivity, stability and micro sample requirement. Compared with other traditional methods, the interaction of multi-component in the TCMs was taken into account, which provides new ideas for the search of TCMs. Here, we presented a brief introduction on the progress on the topic, which promoted the development of electrochemical oscillation and the standardization of TCMs in the last twenty years. Electrochemical oscillation method is cheap, sensitive, fast, stable and convenient for the identification and quality control of TCMs. Reaction systems and the visualization of the fingerprints can be improved in the future.

Summary

Introduction

The identification is one of the important tasks in traditional Chinese medicines (TCMs). The microstructure-based method uses a microscope to observe the tissue and cell structure. It is a fast technology, but it is affected by harvest seasons and storage conditions [2]. Molecular biology technology (DNA barcode technology) has been applied in the identification of TCMs [9,10,11]. It cannot be used for the identification of TCMs with post-treatment due to DNA damage. Future perspectives of electrochemical oscillation have been discussed as well
