[Abstract] Objective To explore and uncover the hot topics and developing trend of Chimonanthus nitens. Methods The related articles about Chimonanthus nitens published in CNKI from January 1, 1996 to September 30, 2017 were retrieved. Excel and SPSS were used for descriptive analysis, and the CiteSpace was used to draw the knowledge maping and take co-occurrence and clustering analysis of key words. Results The time from 2005 to 2016 was the fast development period of researches about Chimonanthus nitens. The author, Liu Zhongda, had posted the most papers about Chimonanthus nitens and the organization that published the most articles was Lishui Hospital of Traditional Chinese Medicine. The hot topic was chemical compositions of Chimonanthus nitens. Research trends were the researches of chemical compositions, traditional She Medicine, conservation of resources and genetic diversity. Conclusion Analysis on the hot topics and tendency of Chimonanthus nitens will provide a certain reference for its further development and utilization.

山蠟梅又名食凉茶,是畲族习用药材,为蜡梅科植物柳叶蜡梅(Chimonanthus salicifolius S.Y.Hu)或浙江蜡梅(Chimonanthus zhejiangensis M.C.Liu)的干燥叶,具有祛风解表、清热解毒、理气健脾、消导止泻之功效[1]。山蜡梅中主要含有挥发油、黄酮、生物碱等化学成分[2],临床上常用于治疗消化不良、脾虚泄泻、盆腔炎等病证[3-4]。近年来,山蜡梅化学成分、药理作用、临床疗效、栽培技术等文献逐渐增多,难以通过文献综述彻底阐明山蜡梅的研究热点及趋势。科学知识图谱的分析方法可以更好地体现山蜡梅研究中的科学内涵。
科学知识图谱是以知识域(knowledge domain)为对象,显示科学知识的发展进程和结构关系的图像,其可视化程度高,能够显示某一研究领域在一定时期发展的趋势与动向,并展示出该领域研究的演进历程[5-6]。本文拟基于该方法,分析近20年山蜡梅研究中的热点及趋势,促进其资源开发及利用。……
