[CiteSpace knowledge map analysis of research progress on Tripterygium wilfordii toxicity].

This study systematically searched CNKI and Web of Science(WoS) for the research papers on the toxicity of Tripterygium wilfordii included from database inception to August 31, 2021, and visually displayed the authors, research institutions, keywords, and other contents using bibliometrics and CiteSpace 5.8.3. Furthermore, the current situation and research progress on T. wilfordii safety were also analyzed based on information extraction to find the research hotspot, evolution path, and development trend, and to provide references for future research. A total of 1 876 Chinese papers and 243 English papers were included in the study. The analysis of authors showed that WANG Qi and ZHANG Luyong had the most publications in Chinese and English papers, respectively. According to the analysis of research institutions, National Institutes for Food and Drug Control and China Pharmaceutical University possessed the largest number of Chinese and English papers, respectively, but there was less cooperation between them. The analysis of keywords in Chinese and English papers showed that the research contents of the safety of T. wilfordii mainly focused on clinical monitoring, mechanism, dosage form improvement, quality standard, component analysis, monomer research, efficiency and toxicity reduction, etc. Metabonomics, tripterine, and the underlying mechanism of toxicity were the research hotspots in the future. At present, the research on the toxicity of T. wilfordii is still under development. It is necessary to highlight the in-depth research and strengthen the inter-group and inter-region cooperation of authors or institutions to provide references for the research on the toxicity of T. wilfordii.
