In order to understand the overall situation of tea saponin research at home and abroad, and explore the hot issues and research trends, the annual publications, subjects involved, funding status, countries researched and institutes, lead author, quantity of master and doctoral dissertations, source journals of the research literatures of tea saponin, which were retrieved from the Web of Science and CNKI Chinese journal database from 1990 to 2019, were analyzed by using bibliometric analysis and CiteSpace keyword co-occurrence network analysis method. According to the result, the researches on tea saponin have been in the stage of rapid development since 2004, and the total quantity of the literatures and citations showed a year-by-year growth trend on the whole. The researches on tea saponin were mainly funded by national funds, and among 34 provincial administrative regions, more financial support was granted to Zhejiang and Hunan province. Globally, the research on tea saponin was mainly concentrated in China, followed by Japan and the USA. South China Agricultural University was the institution publishing the largest number of Chinese papers, and Zhejiang University was the institution publishing the largest number of SCI papers; YOSHIKAWA M of Kyoto Pharmaceutical University published the largest number of SCI papers. Currently, the hot issues of the researches on tea saponin mainly concentrated on in vitro pharmacological activity (antioxidant activity), rumen fermentation, methanogenesis and other directions. Besides, although constantly innovating and optimizing the methods of extracting tea saponin was not the research front, a lot of science researchers have constantly focused on it.
