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-1beta, 6alpha-diol (6), (E) -5-hydroxy-N-isobutylpentadec-2-enamide (7), syringaresinol (8), quercetin (9), ethyl laurate (10), ethyl caffeate (11), ferulic acid (12), alpha-spinasterol (13), stigmasterol (14), beta-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.
