Objective:
To study the chemical constituents from Cyathea spinulosa.
Methods:
Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectral methods.
Results:
Eight compounds were isolated from the ethanol extract of Cyathea spinulosa and identified as stigmast-4-ene-3,6-dione (1), stigmast-3,6-dione (2), ergosterol (3), protocatechuic aldehyde (4), 1-O-beta-D-glucopyranosyl-(2S,3R,4E,8Z)-2-[(2-hydroxyoctadecanoyl) amido]-4,8- octadecadiene-1,3-diol (5), (2S,3S, 4R)-2-[(2'R) -2'-hydroxytetracosanoylamino]-1,3,4-octadecanetriol (6), beta-sitosterol (7), daucosterol (8).
Conclusion:
Compounds 1-6 are isolated from this plant for the first time.
