[Research hotspots and trends of Hedysari Radix: based on CiteSpace knowledge map].

This study aims to summarize the research hotspots of Hedysari Radix and predict the research trend with bibliometric methods, which is expected to serve as a reference for future research. CiteSpace V 5.8.R2 was employed for visualization of the number, authors, author affiliations, journals, funds, and keywords of the Chinese and English articles on Hedysari Radix in China National Knowledge Infrastructure(CNKI) and Web of Science(WOS) from 2001 to 2021. A total of 693 Chinese articles and 167 English articles were finally included. According to the knowledge map, most of the articles were from China and the authors from China had a close cooperation with the related institutions in the United States and Australia. Gansu University of Chinese Medicine(288) and Lanzhou University(151) respectively came out on top of the author affiliations in the number of Chinese and English articles. The journals were mainly about Chinese medicine, mainly including Chinese Journal of Information on Traditional Chinese Medicine and Evidence-based Complementary and Alternative Medicine. Papers(191 in Chinese and 60 in English) funded by National Natural Science Foundation of China were the most. Keyword analysis suggested that the main research directions were pharmacological action and mechanism, component analysis, content determination, and industrialization of medicinal materials of Hedysari Radix and that the research hotspots were the prevention and treatment of diabetes and its complications, tumors, myocardial injury, liver fibrosis and other diseases with active components such as polysaccharides, ultrafiltrate, formononetin, and calycosin. The targets, signaling pathways, and genes related to the anti-tumor, heart protection, prevention and treatment of diabetes and its complications, and regulation of immunity should be further studied.
