Analysis on the Development Trend and Hot Spots of Gastrodia Elata Bl. Research Based on Bibliometrics

OBJECTIVE To generalize the main research hotspots of Gastrodia elata Bl. and summarized the pharmacological activities of Gastrodia elata Bl. by analyzed the literatures in the field of Gastrodia elata Bl. research from 2000 to 2020, so as to provide reference for Gastrodia elata Bl. researchers. METHODS Based on China National Knowledge Infrastructure(CNKI) China Journal Fulltext Database(CJFD) and China Citation Database-CNKI Edition(CCD), using literature metrology method of paper published year, periodical distribution, subject distribution, highly cited, foundation, core authors, institutions, keywords, and highlight the word frequency analysis. RESULTS The total of Gastrodia elata Bl. papers published was 11 598 from 2000 to 2020, and the number of articles had increased, involving more than 40 multidisciplinary fields, and the field of traditional Chinese medicine was the most widely studied. The main research institutions were universities of traditional Chinese medicine, with the most funding from the National Natural Science Foundation of China. The cooperation between authors and institutions was loose, and the literatures with high citation frequency had been published for a long time. The development trend of Gastrodia elata Bl. had changed from cultivation and breeding to pharmacological activity and medicinal effect. The research focus was to explore the sedative hypnosis, anti-convulsion, anti-inflammatory, neuroprotective and anti-anxiety and depression effects of Gastrodia elata Bl., as well as the optimization of the extraction process of active components. CONCLUSION The future hot spot of Gastrodia elata Bl. is exploring new pharmacological activities and clinical efficacy verification. Researchers should deepen cooperation among institutions. This study will provide a reference for subsequent scholars to quickly understand the research focus and literature retrieval in the field of Gastrodia elata Bl..
