Two novel C-glycosylflavones, apigenin-6-C-α-L-arabinopyranosyl-(1-4)-α-L-rhamnopyranoside (hemsleyanoside, 1) and apigenin-8-C-α-L-arabinopyranosyl- (1-4)-α-L-rhamno-pyranoside (isohemsleyanoside, 2), together w...Two novel C-glycosylflavones, apigenin-6-C-α-L-arabinopyranosyl-(1-4)-α-L-rhamnopyranoside (hemsleyanoside, 1) and apigenin-8-C-α-L-arabinopyranosyl- (1-4)-α-L-rhamno-pyranoside (isohemsleyanoside, 2), together with a known compound (apigenin-6,8-di-C-β-D-glucopyranoside, 3), were isolated from the 95% EtOH extract of Tetrastigma hemsleyanum Diels et Gilg. Their structures were elucidated by chemical evidence and spectral analysis.展开更多
[目的]基于CiteSpace,分析在2000—2022年发表的三叶青中英文文献、研究热点和发展趋势,为今后研究提供参考。[方法]检索中国知网(CNKI)及Web of Science,运用文献计量学及CiteSpace 6.1.R3软件对年发文量、发文期刊、作者、研究机构、...[目的]基于CiteSpace,分析在2000—2022年发表的三叶青中英文文献、研究热点和发展趋势,为今后研究提供参考。[方法]检索中国知网(CNKI)及Web of Science,运用文献计量学及CiteSpace 6.1.R3软件对年发文量、发文期刊、作者、研究机构、关键词共现、聚类和突变7个方面进行可视化网络分析,并结合信息提取的方法对三叶青研究现状及发展趋势进行分析。[结果]《浙江农业科学》和《International of Journal Biological Macromolecules》分别是发表中文、英文文献最多的期刊。彭昕是三叶青研究的中、英文文献主要核心作者,浙江医药高等专科学校和浙江大学分别是中、英文高发文量的研究机构。关键词分析研究表明目前对三叶青主要围绕基础性相关性研究,预测热点研究方向还应是抗炎、抗肿瘤等药理机制和药效物质的挖掘。[结论]三叶青相关研究仍处于发展阶段,需注重研究的深入并加强作者和研究机构的合作,同时还应继续围绕抗炎、抗肿瘤药理、药效和深加工产品开发。展开更多
