Chemical Constituents from the Aerial Part of Echinacea purpurea
摘要
Abstract
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 recrystallization.Their structures were elucidated on the basis of physiochemical properties and spectral analysis.Results:Sixteen compounds were isolated and identified as (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),syringaresinol (8),quercetin (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.关键词
