摘要
目的:研究灯盏花Erigeron breviscapus的化学成分。方法:利用各种色谱方法进行成分分离纯化,根据理化性质和波谱分析鉴定化合物结构。结果:分离得到12个化合物,分别鉴定为槲皮素-3-O-β-D-葡萄糖苷(1)、5,7-二羟基色原酮(2)、3-O-咖啡酰-γ-奎尼内酯(3)、柚皮素(4)、3,5-二-O-咖啡酰奎尼酸(5)、3,4-二-O-咖啡酰奎尼酸(6)、4,5-二-O-咖啡酰奎尼酸(7)、1,3-二-O-咖啡酰奎尼酸(8)、1,5-二-O-咖啡酰奎尼酸(9)、3-O-咖啡酰奎尼酸(10)、4-O-咖啡酰奎尼酸(11)和绿原酸(12)。结论:化合物1~4为首次从灯盏花中分离得到。
Objective:To study the chemical constituents from herbs of Erigeron breviscapus.Method:The compounds were isolated and purified by various chromatographic techniques.Their structures were identified on the basis of physicochemical properties and spectral analysis.Result:Twelve compounds were isolated and structurally identified as quercetin-3-O-β-D-glucoside(1),5,7-dihydroxychromone(2),3-O-caffeoyl-γ-quinide(3),naringenin(4),3,5-di-O-caffeoylquinic acid(5),3,4-di-O-caffeoylquinic acid(6),4,5-di-O-caffeoylquinic acid(7),1,3-di-O-caffeoylquinic acid(8),1,5-di-O-caffeoylquinic acid(9),3-O-caffeoylquinic acid(10),4-O-caffeoylquinic acid(11) and chlorogenic acid(12).Conclusion:Compounds 1-4 were isolated from this plant for the first time.
