目的研究我国特有属药用植物裸蒴Gymnotheca chinensis的化学成分。方法通过硅胶柱色谱及高效液相制备色谱分离纯化,以波谱分析和化学方法鉴定结构。结果从裸蒴全草乙醇提取物中分离得到了一个苯酚衍生物,鉴定为(7R)-苯甲酸-7-对羟苯基-乙二醇-8-单酯。结论该苯酚衍生物为首次报道的新化合物,命名为裸蒴酚甲。 Objective To study the chemical composition of Gymnotheca chinensis, a species of medicinal plant in China. Methods The compounds were isolated and purified by silica gel column chromatography and high performance liquid chromatography (HPLC). Their structures were identified by spectral analysis and chemical methods. Results A phenol derivative was isolated from the ethanol extract of Allium urophylla and identified as (7R) - benzoic acid - 7 - p - hydroxyphenyl - ethylene glycol - 8 - monoester. Conclusion The phenol derivative was first reported as a new compound, named as Arenolol.
