RESUMEN
To comprehensively understand the developing state of Polygonati 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.
