摘 要:目的:研究鬼针草治疗糖尿病的有效化学成分。方法:采用80%乙醇渗漉提取,硅胶,反相硅胶,Sephadex-LH20柱层析分离纯化,化学反应和波谱分析鉴定其化学结构。结果:从鬼针草中得到槲皮素(Ⅰ)、金丝桃苷(Ⅱ)、槲皮素-7-O-鼠李糖苷(Ⅲ)、6,7,3’,4’-四羟基橙酮(Ⅳ)、4,5-双咖啡sg酰奎宁酸(Ⅴ)、豆甾醇-3-O-葡萄糖苷(Ⅵ)、3,4-二羟基苯甲酸乙酯(Ⅶ)、奥卡宁(Ⅷ)、木犀草素(Ⅸ)。结论:以上化合物除奥卡宁、金丝桃苷外,其余7个化合物均为首次从鬼针草中分离得到。Objective:To investigate the bioactive chemical constituents in Bidens bipinnata L. for treatment of diabetes. Methods: Extraction was done with 80% EtOH; isolation and purification were carried out on silica gel,C18 silica gel column, and Sephadex-LH20 column; and the chemical structures of the products were identified by physicochemical properties and spectral analysis. Results: Nine compounds were obtained from Bidens bipinnata L. and their chemical structures were identified as: quercitin( Ⅰ ), hyperoside ( Ⅱ ) ,quercitin-7-O-rhamnopyranoside( Ⅲ ) ,6,7,3 '4 '-tetrahydroxy aurone( Ⅳ ) ,4,5-di-O- caffeoyl quinic acid( Ⅴ ) ,stigmasterol 3-O-glucopyranoside ( Ⅵ ), ethyl 3,4-dihydroxybenzoate( Ⅶ ), okanin( Ⅷ ), and luteolin( Ⅸ ). Conelusion: Except for okanin and hyperoside,the rest 7 compounds are isolated from the plant for the first time.
