基于Pub Med数据库谷物多糖研究文献计量分析

Quantitative Analysis of Cereal Polysaccharide Based on Pub Med Database

了解谷物多糖中文献分布特点和主要研究现状,为进一步的科学研究提供基础。基于文献计量学的方法对Pub Med数据库收录的2007—2016年谷物多糖相关文献从论文发表年限、核心作者、期刊、国别等方面进行统计分析。结果表明,有关谷物多糖论文767篇,发文量居前3位的国家分别是英国、美国、荷兰,我国位列第6位,且文献所占比重只有1.56%。谷物多糖的研究热点包括淀粉、大麦、抗性淀粉、阿糖基木聚糖、膳食纤维、β-葡聚糖、胚乳等。近年来,谷物多糖文献发表数量呈逐年平稳增长,但我国在谷物多糖研究领域与发达国家还存在着一定的差距。

In order to provide a basis for further scientific research,the current status of cereal polysaccharide,the distribution characteristics of the papers were surveyed.Based on the analysis methods of document metrology,Pub Med database was viewed as the data sources,moreover,the publication date,main author,journal and place of publication during 2007-2016 were analyzed statistically.The results showed that a total of 767 papers on cereal polysaccharide were retrieved,the top 3 countries were Britain,the United States and Holland,China ranked the sixth,and the proportion of the literature was only 1.56%.The research hotspots of cereal polysaccharide focused on several fields-starch,barley,resistant starch,Arabinoxylans,dietary fiber,β-glucan,endosperm and so on.In recent years,the number of cereal polysaccharide publications had been increasing steadily year by year,but there was still a certain gap between China and developed countries in the field of grain polysaccharide research.
