Research trend analysis of Leucojum aestivum based on Citespace visualization software

Abstract

The secondary metabolite of Leucojum aestivum lycorine, is of high medicinal value and has attracted much attention internationally. Therefore, it is essential to review and analyze the existing literature on L. aestivum to clarify the research progress, research bottlenecks, and applications of lycorine in landscapes. In this study, we used the Web of Science (WOS) and CNKI Chinese journal database as data sources to analyze the bibliometric analysis of L. aestivum-related literature in terms of the number of publications, journal sources, research institutions, keywords, and co-cited literature using Citespace visualization software. The results showed that the number of L. aestivum-related studies decreased compared to previous years, but the number of publications showed a high growth trend in this research frontier. Bulgaria has a significant dominance in L. aestivum-related research, while China has fewer publications in this field but focuses more on the frontiers of the discipline. The frontiers of L. aestivum research concentrate on improving in vitro culture devices, changing plant culture strategies, and adding chemical additives to improve the yield of compounds in plants; new methods for lycorine synthesis; identification of ornamental plant species and detection of compounds by electrochemical methods; practical applications of lycorine in medicine and its mechanism of action. It is inferred that future research will focus on the ornamental value, medicinal value, cultivation methods, and innovation of lycorine synthesis methods of aestivum.
