摘要
首次对广东九节属植物Psychotria sp.的化学成分进行系统研究,从其甲醇总提取物的乙酸乙酯溶解部分,通过硅胶柱层析得到四个多酚类成分。应用物理常数对照和现代波谱分析技术对其进行结构研究,确定其为:11-O-丁香酰矮地茶素(1)、岩白菜素(2)、没食子酸(3)和没食子酸甲酯(4)。化合物1,2,3,4均首次在此属植物中发现。
The chemical constituents and their biological activities of the Psychotria sp.were studied.Four polyphenolic compounds were isolated from the Psychotria sp.collected from Guangdong Qingpin TCM center.Their structures were determined as 11-O-syringylbergenin(1),(2 R,3 S,4S,4a R,10b S)(-)-bergenin(2),gallic acid(3),methyl gallate(4) mainly by spectroscopic analysis.All of these compounds are firstly obtained in genus of Psychotria.
