基于SCIE生药分子鉴定领域的文献计量学分析
Bibliometrics analysis on identification of molecula pharmacognosyin based on Web of Science
目的 分析当前生药分子鉴定领域的文献特征,总结和归纳该领域的研究现状,探讨生药分子鉴定领域未来的发展方向.方法 以Web of Science中的科学引文索引扩展版数据库(SCI expanded,SCIE)为数据来源,检索2000-2016年生药分子鉴定领域的相关文献,运用文献计量学方法和Gephi软件,从年代、期刊、发文机构、国家/地区及生药分子鉴定的技术方法等方面进行分析.结果 共纳入有效文献5108篇,涉及3720位作者,1695家发文机构,421种期刊,发文国家/地区主要以中国、美国、韩国为主;研究内容以长春花、人参、烟草、小麦、青蒿为主,技术方法以随机扩增多态DNA技术、微卫星法和扩增片段长度多态性为主,研究热点主要集中在生药分子鉴定中的多基源鉴定、产地鉴定及种群遗传学和分子谱系地理学.结论 生药分子鉴定仍处于上升的发展阶段,分子鉴定的技术方法及研究的中药品种在不断扩展和延伸.
更多Objective To analyze the literature characteristics on molecular identification of pharmacognosy, summarize the current research situation and trend in the field and to provide a reference for relative researchers. Methods The papers relevant to molecular identification included in SCIE were statistically analyzed by biblimetric methods from the aspects of publishing year,journals disbution, author's unit,author's country or region and technique.And the papers also use the visualization techonology to visual the links between the keywords. Results The total number of the literature for analyzing was 5108, the numbers of papers increased gradually.These paper involved 3720 authors, 1695 organizations. and 421 journals. Authors of the papers mainly from China, the United States and Korea. The traditional Chinese medicine involved were Catharanthusroseus, Panax ginseng, Tobacco,wheat, Artemisia annua. The relative identification technology top 5 were RAPD, microsatellite, AFLP, ISSR, HPLC.Based on visiualization technology, we found the current research hotspots were base source identification, habitats identification, population genetics and molecular phylogeography. Conclusions The research of molecular identification of pharmacognosyin were on the rise. The identification technology and species studied will extend ulteriorly.
