Bibliometric and visual analysis of quercetin in kidney disease from 2000 to 2022

Due to the complexity and challenges in the treatment of kidney diseases, it is particularly important to explore new therapeutic approaches, such as natural plant components, to enhance efficacy and reduce toxic side effects. In recent years, quercetin has received widespread attention from researchers in the field of kidney diseases, and a series of clinical and animal experiments have been conducted, resulting in a large number of academic papers and publications. This study conducts a bibliometric analysis to understand the current research status, research hotspots, and development trends of quercetin in kidney diseases, aiming to provide potential research directions for further studies on the treatment of kidney diseases.

Publications were retrieved related to quercetin and the kidney from the Science Citation Index Expanded database within the Web of Science Core Collection. Bibliometric analysis was performed, including annual publication analysis, keyword co-occurrence analysis, collaboration network analysis, and citation analysis, using software such as VOSviewer, CiteSpace, Bibliometrix package based on R software, and Microsoft Excel. The results of the bibliometric analysis were visualized.

This study included a total of 1253 literature items related to quercetin and kidney diseases between the years 2000 and 2022. The annual publication output showed an overall exponential growth trend. The most frequent keywords were "quercetin" followed by "oxidative stress." J Ethnopharmacol was the journal with the highest publication output in this field. Yin Xiaoxing was the most prolific author, and King Saud University was the institution with the highest publication count. As for countries, China had the highest publication count.

Through bibliometrics analysis, it has been found that quercetin has received increasing attention from researchers in the field of kidney diseases. The oxidative stress and antioxidant properties of quercetin are the main areas of focus. Diabetic nephropathy is the primary disease being studied. Network pharmacology is an emerging research method, with a particular emphasis on studying the relevant signaling pathways.
