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

Abstract

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. Because of 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 Scientific Citation Index Expanded (SCIE) database of the WoS with a topic search related to electrochemical analysis of flavonoids. Results: In this paper, the research progress in electrochemical analysis of flavonoids has been reviewed. Antioxidant activity of flavonoids is the hot area that attracted considerable attention because it directly affects the application of flavonoids. Different analytical methods also received attention of researchers, such as cyclic voltammetry and capillary electrophoresis. This is because 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. Three peaks of this research area can be found as 2004-2005, 2011-2013 and 2016-2018. Although the different countries are conducting research on electrochemical analysis of flavonoids, most of these institutions are not related to each other.
