This paper aims to characterize the knowledge field of Grifola frondosa and analyze its research themes and trends. CiteSpace, a powerful bibliometric analysis tool, was adopted to visualize the knowledge field of G. frondosa research for facilitating this current study. A total of 747 articles and reviews retrieved from the Web of Science Core Collection (WoSCC) database between 1998 and 2022 were analyzed by CiteSpace. It was found that China and Japan are the most influential countries in G. frondosa research. Secondly, polysaccharide, bioactivity, structural characterization, and submerged culture are the main themes of G. frondosa research, among which bioactivity and structural characterization are the current research hotspots. Finally, selenium polysaccharide and gut microbiota may be the emerging trends in G. frondosa research in the future. This study could help researchers discern the evolution and future trends of G. frondosa research and provide a reference for related research work.
