摘要: 采用正相硅胶色谱柱、Sephadex LH-20以及制备HPLC等色谱方法对羊耳菊进行分离纯化,并通过理化常数和波谱数据鉴定其化学结构。深入研究羊耳菊干燥全草的咖啡酰基奎宁酸类化学成分。从羊耳菊中分离得到8个咖啡酰基奎宁酸类化合物,分别为1,5-O-二咖啡酰基奎宁酸(1)、1,3,5-O-三咖啡酰基奎宁酸(2)、3,5-O-二咖啡酰基奎宁酸甲酯(3)、3,4-O-二咖啡酰基奎宁酸甲酯(4)、3,4-O-二咖啡酰基奎宁酸乙酯(5)、4,5-O-二咖啡酰基奎宁酸乙酯(6)、3,5-O-二咖啡酰基奎宁酸(7)、 3,4-O-二咖啡酰基奎宁酸(8)。化合物1~3为从该植物中首次分离得到,4~6从该属植物中首次分离得到。

Abstract: The caffeoylquinic acid derivatives from the whole plant of Inula cappa were isolated by using a combination of various chromatographic techniques including silica gel chromatography,Sephadex LH-20 chromatography and preparative HPLC.Their structures were identified by their physical-chemical properties and spectroscopic analysis. Eight compounds were isolated and identified as 1,5-di-O-caffeoylquinic acid(1),1,3,5-tri-O-caffeoylquinic acid(2),methyl-3,5-di-O-caffeoyl quinate(3), methyl-3,4-di-O-caffeoylquinate(4),ethyl-3,4-di-O-caffeoylquinate(5),ethyl-4,5-di-O-caffcoylquinate(6),3,5-di-O-caffeoylquinic acid(7), 3,4-di-O-affeoylquinic acid(8).Compounds 1-3 were isolated from this species for the first time.Compounds 4-6 were found from the genus firstly.

Key words: Inula cappa, chemical constituent, caffeoylquinic acid derivative
