摘要
目的:研究紫锥菊地上部分的化学成分。方法:通过反复的硅胶、ODS、D101大孔树脂、MCI、SephadexLH-20柱色谱以及重结晶等方法分离纯化,通过理化性质和波谱分析技术鉴定化合物的结构。结果:从紫锥菊地上部分分离鉴定了16个化合物,分别为:(2S)-1-O-octacosanoyl glycerol(1)、(5R,6S)-6-hydroxy-6-((E)-3-hydroxybut-1-enyl)-1,1,5-trimethylcyclohexanone(2)、(3S,6E,10R)-3,10,11-trihydroxy-3,7,11-trimethyl-dodeca-1,6-diene(3)、negunfurol(4)、schensianol A(5)、ent-4(15)-eudesmene-1β,6α-diol(6)、(E)-5-hydroxy-N-isobutylpentadec-2-enamide(7)、丁香脂素(8)、槲皮素(9)、月桂酸乙酯(10)、咖啡酸乙酯(11)、阿魏酸(12)、α-菠甾醇(13)、豆甾醇(14)、β-胡萝卜苷(15)、二十八烷酸(16)。结论:其中,化合物1~5为首次从菊科植物中分离得到,化合物6、7、9、10、12为首次从松果菊属植物中分离得到,化合物15、16为首次从该植物中分离得到。
Objective : To study the chemical constituents of the aerial part of Echinacea purpurea. Methods : The compounds were separated and purified by repeatedly silica gel, ODS, D101 macroporous resin, MCI , Sephadex LH-20 column chromatography and re-crystallization . Their structures were elucidated on the basis of physiochemical properties and spectral analysis. Results : Sixteen com-pounds were isolated and identified as (2S)-1-O-octacosanoyl glycerol (1) , (5R,6S)-6-hydroxy-6-( (E)-3-hydroxybut-l-enyl)-1,1, 5-trimethylcyclohexanone ( 2 ) , ( 3 S,6E, 10R) -3,10,11-trihydroxy-3 ,7 ,11 -trimethyl-dodeca-1,6-diene ( 3 ), negunfurol ( 4 ) , schens-ianol A ( 5 ) , ent-4 ( 15 ) -eudesmene-1β,6α-diol ( 6 ) , (E) -5-hydroxy-N-isobutylpentadec-2 -enamide ( 7 ) , syringaresinol ( 8 ) , querce-tin (9) ,ethyl laurate (10) ,ethyl caffeate (11) ,ferulic acid (12) ,α-spinasterol (13) ,stigmasterol (14) ,β-daucosterol (15) , octacosanoic acid (16) . Conclusion : Compound 1 - 5 are isolated from the Asteraceae for the first time , compound 6,7,9,10,12 are isolated from genus of Echinacea for the first time, compound 15,16 are isolated from this plant for the first time.
