Abstract:

As an important Chinese herbal medicine and industrial raw material plant, giant knotweed (Polygonum cuspidatum) is widely distributed at home and abroad. To understand giant knotweed research status and trend accurately is significant for its planting and further utilization. Based on literature retrieved from the CNKI Chinese periodical database and the Web of Science core database of 2002-2022, the current situation, dynamics and frontier hotspots of giant knotweed research were systematically and comprehensively analyzed by applying the bibliometric visualization tools of CiteSpace and VOSviewer. The research on giant knotweed has gained rising attention at home and abroad since 2002. In China, the most influential research institutions are the Chinese Academy of Sciences, the Chinese Academy of Agricultural Sciences and Sichuan University etc. From the international perspective, China is the country with the highest influence in the research cooperation of giant knotweed, with 44.8% of the world’s published literature in this field. The hot topics of giant knotweed research at home and abroad have formed 17 clusters. Domestic research mainly focuses on the medicinal value, growth characteristics, regeneration and in vitro culture of giant knotweed, as well as the extraction, efficacy and utilization of functional components as resveratrol, glycoside, emodin, chlorogenic acid, and total anthraquinone. International research hot topics include the extraction and analysis of anthraquinone compounds, resveratrol and other functional components, the medical and health uses such as anti-oxidation effect and cell proliferation inhibition, the identification of new active substances, the molecular mechanism of action, the synthetic biology, the energy and pesticide utilization, the biological invasion and biological control etc. This study confirmed the advantages and influence of Chinese research institutions and researchers, and provided directions for deepening the research on giant knotweed (Polygonum cuspidatum).
