Progress in the Electrochemical Analysis of Flavonoids: A Scientometric Analysis in CiteSpace

Background: Flavonoids are a large class of phenolic compounds, which generally refer to two benzene rings (A ring, B ring) with phenolic hydroxyl groups connected to each other through three central carbon atoms, that is, a series of C6-C3-C6 basic core compounds. Due to its potential medicinal value, the research on flavonoids has aroused great interest. Methods: This review aims to identify the research progress and development trends of electrochemical analysis of flavonoids. We retrieved published papers (1998-2020) from the Scientific Citation Index Expanded (SCIE) database of the WoS with a topic search related to the electrochemical analysis of flavonoids. Results: In this paper, the research progress in electrochemical analysis of flavonoids has been reviewed. The antioxidant activity of flavonoids has attracted considerable attention because it directly affects the application of flavonoids. Different analytical methods also received the attention of researchers, such as cyclic voltammetry and capillary electrophoresis. This is because the advanced analysis technology can be useful for evaluating the property of flavonoids. Conclusion: The research progress and development trends were analyzed based on CiteSpace software of text mining and visualization. Most research papers on this topic were published in the years 2004-2005, 2011-2013 and 2016-2018. Different countries are conducting research on the electrochemical analysis of flavonoids, which are not related to each other.
