“十二五”(2011—2015年)黄精科技文献计量分析

Quantitative analysis on scientific and technical literature of Polygonati Rhizoma in recent five years

黄精是传统补益中药,开发利用正处于快速发展阶段。为全面了解"十二五"期间黄精的发展状况,以中国期刊全文数据库(CJFD)和Web of Science为文献来源,检索了2011—2015年有关黄精研究的文献,对文献年代、期刊、作者、作者单位、省份及研究主题分布进行统计学分析;并利用文献计量工具Ucinet和Net Draw研究了文献关键词共现网络特性。结果表明,黄精研究主要集中在国内,并且正处于稳步增长阶段;研究主题广泛,涉及种质资源、种苗繁育、栽培技术、生物学特性、化学成分和药理作用及临床应用等领域,已形成较稳定的研究机构和团队;研究对象主要为3种黄精。我国黄精研究已取得显著成果,但种质资源退化,种苗繁育、栽培技术、提取分离工艺落后导致的供需矛盾仍旧困扰我国黄精的产业化进程。种苗繁育、规范化种植、工艺优化及食品保健品开发是未来黄精研究的热点。

To comprehensively understand the developing state ofPolygonati Rhizoma （PR） studies in the period of Twelfth-five-year Plan, document retrieval was performed on the literature sources of Chinese Journal Full-text Database and Web of Science during 2011--2015. The literature distribution characteristics of time, journals, authors, author affiliations, author＇s regions, and research subjects about PR were analyzed statistically by the method of bibliometrics. Ucinet and NetDraw were applied to conducting online co-occurrence graph of keywords. The results showed that China is the leader of research on PR. Distribution of journals is more concentrated, taking the following four journals as representation--Lishizhen Medicine and Materia Medica Research, Chinese Journal of Experimental Traditional Medical Formulae, Seed, and Journal of Anhui Agricultural Sciences. The research subjects have a wide array of sources, including germplasm resources, seed breeding, cultivation techniques, biological property, chemistry, pharmacology, and clinical application. The research institutes and teams have been formed. The study on PR has made remarkable achievements, but the germplasm resources of PR have degenerated continually, seed breeding, cultivation techniques, extraction and isolation technology are less developed. The supply of PR fails to meet the consumption demand. It indicates that the seed propagation, standardized artificial planting, extraction process optimization, food, and health care product development will be hot research areas.
