The knowledge graph analysis of literature information in the research field of Lycium barbarum polysaccharides(LBPs) can provide theoretical reference for researchers to accurately grasp the research progress and development trend of this field.In this study,the Chinese and English literatures of LBPs research retrieved by CNKI and WOS were used as data sources.The authors,research institutions and keywords included in the literature were statistically analyzed and visually displayed using bibliometric methods and CiteSpace software.A total of 718 Chinese and 387 English literatures were included in this study.The author with the most Chinese articles was Zhang Shenghua of Huazhong Agricultural University,while the author with the most English articles was KWOOFAI SO of the University of Hong Kong.The research institution with the most articles in Chinese and English were Ningxia Medical University and the University of Hong Kong respectively.The research on LBPs had regional characteristics.The keyword analysis of the literatures showed that the research hotspots of LBPs in Chinese and English literatures focused around the biological activity currently.The research frontier of the Chinese literature of LBPs was on the oxidative stress,anti-ultraviolet radiation,and immune synergists.The research frontier of the English literature of LBP was on the reproductive system,DNA damage,autophagy and so on.The results showed that the research on the quality,mechanism of biological activity,and application research were current research hotspots and possible future research directions of LBPs.
