PMID 23019903

Abstract

To study the chemical constituents from Cyathea spinulosa. Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectral methods. 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). Compounds 1-6 are isolated from this plant for the first time.
