基于CiteSpace的茶黄素研究现状可视化分析

Visualization Analysis in Research Status of Theaflavins Based on CiteSpace

为把握茶黄素研究的进展和热点,客观反映不同国家、作者、研究机构以及期刊在该领域的影响力,本研究运用文献计量学和CiteSpace可视化分析软件,对1964—2021年被WOS(Web of Science)数据库收录的725篇和被CNKI (China National Knowledge Infrastructure,中国知网)数据库收录的391篇茶黄素(Theaflavin/Theaflavins,TF/TFs)文献进行分析。结果表明,研究报道茶黄素最多的国家依次为中国、印度、美国和日本;日本长崎大学的Tanaka研究最为深入;与茶黄素类相关的儿茶素氧化产物研究报道最多;刘仲华、江和源、屠幼英是国内茶黄素研究的引领者;《茶叶科学》和《Food Science Technology》是茶黄素发文量最高的期刊;关键词分析显示中文文献研究侧重于茶黄素的制备分离和其对红茶品质的影响,英文文献侧重于茶黄素的药理研究,且茶黄素的制备分离及其药理功效仍为未来研究的热点。

Aiming to grasp the progress and hotspots of theaflavin research and objectively reflect the influence of different countries, authors, research institutions and journals in this field, bibliometrics and CiteSpace.5.7.R5 W visualization analysis software were used in this study to analyze 725 and 391 Theaflavin/Theaflavins(TF/TFs)literatures collected by Web of Science(WOS) and China National Knowledge Infrastructure(CNKI) from 1964 to 2021. It was found that China, India, the United States and Japan were the countries with the most research on theaflavin. Tanaka of Nagasaki University in Japan had the most researches. The catechin oxidation products related to theaflavins had been reported the most. Liu Zhonghua, Jiang Heyuan and Tu Youying were the leaders of theaflavins research in China. Food Science Technology and Journal of Tea Science were the English and Chinese journals with the highest publication volume of theaflavin. Keyword analysis showed that Chinese literature mainly focused on the preparation and separation of theaflavins and their effects on the quality of black tea. English literature focused on the pharmacological research of theaflavins, and the preparation and pharmacological effects of theaflavins were still the research hotspots in the future.
