基于文献计量分析芝麻的研究热点与趋势

Status and trends of sesame(Sesamum indicum L.)research based on bibliometric analysis

旨在为芝麻产业发展提供文献支撑,利用CiteSpace及Excel软件,基于2012—2022年Webof Science(WoS)核心合集数据库和中国知网(CNKI)学术期刊数据库中的中文核心期刊,采用文献计量方法对芝麻研究相关文献发文量、主要发文国家、地区、机构和作者,以及研究主题、研究前沿等进行了分析。结果显示:WoS核心合集数据库中,关于芝麻研究的论文发文量整体呈持续上升趋势,主要出自中国、印度、伊朗和美国等国家,中国在发文量和影响力方面有绝对优势;全球有342家机构发表芝麻研究相关论文,其中中国农业科学院、阿扎德大学和河南工业大学发文量最高;全球发文量前10名的作者中9位来自中国农业科学院。CNKI数据库中,芝麻相关文献数量整体趋于下降;有298家机构在芝麻研究领域发表了研究论文,主要发文机构有河南省农业科学院、河南工业大学和中国农业科学院等。国内外芝麻研究热点主要集中在芝麻提取物、芝麻生长、芝麻遗传多样性、抗氧化性、芝麻副产品功能特性、芝麻食品研究和芝麻加工研究等方面。抗氧化方向的研究为近几年的突现热点,有望成为未来芝麻领域的研究热点。

In order to provide literature support for the development of the sesame industry,based on the software of CiteSpace and Excel,and the Web of Science(WoS)Core Collection database and the China National Knowledge Infrastructure(CNKI)academic journal database(ocusing on Chinese core journals)spanning the years 2012 to 2022,a bibliometric analysis was conducted to investigate publication trends,primary contributing nations,regions,institutions,and authors in sesame research,as well as emerging research themes and frontiers.The results revealed that there was a consistent upward trajectory in the volume of research papers on sesame within the WoS Core Collection database,predominantly originating from China,India,Iran,and the United States.Notably,China demonstrated a marked advantage in both the publication volume and their impact.Globally,342 institutions had contributed to sesame research,with prominent contributors including the Chinese Academy of Agricultural Sciences,Azad University,and Henan University of Technology.Remarkably,nine out of the top ten authors with the highest publication volume globally were affiliated with the Chinese Academy of Agricultural Sciences.In contrast,within the CNKI database,there was a declining trend in the overall quantity of sesame-related literature.Nevertheless,298 institutions had published research articles in this field,with notable contributors such as the Henan Academy of Agricultural Sciences,Henan University of Technology,and the Chinese Academy of Agricultural Sciences.The prevailing research interests in sesame,both domestically and internationally,include sesame extract studies,sesame cultivation and sesame genetic diversity exploration,antioxidant investigations,functional attributes of sesame by-products,sesame-based food research,and sesame processing methodologies.Particularly noteworthy is the emergence of antioxidant activity research as a recent focal point,suggesting its potential to become a significant area of inquiry within the sesame research domain in the coming years.
