The aim of this study is to identify thematic trends, landmark articles, influential scientists and journals of metabolomics by exploring the scientific outputs in this field. This work was based on 66,721 bibliographic records retrieved from the Web of Science Core Collection database during 1992-2017. The results show that the USA was the leading country, and the Chinese Academy of Sciences had the largest number of publications. The Proceedings of the National Academy of Sciences of the United States of America was the most influential journal, meanwhile PLOS ONE had the most number of publications. Nicholson was identified as the most prominent scientist with the most number of articles and the highest co-citation counts. Metabolic syndromes and related diseases, disease biomarkers, novel pathways, as well as system biology association studies in metabolomics research, might be closely observed in the coming years.
