title: [Studies on the chemical constituents from the stems of Acanthopanax gracilistylus].
abstract: OBJECTIVE
  To study the chemical constituents from the stems of Acanthopanax gracilistylus.
  
  
  METHODS
  The chemical constituents of the plant were isolated and puried by column chromatography and their structures were elucidated on the basis of physico-chemical properties and spectral data.
  
  
  RESULTS
  Sixteen compounds were isolated and identified as (2S,3S, 4R, 8E)-2-[(2'R)-2'-hydroxy-pentadecanoylamino]-heptacosane-1,3,4-triol-8-ene(1a),(2S,3S,4R,8E)-2-[(2'R)-2'-hydroxy-octadecanoylamino]-lignocer-ane-1,3,4-triol-8-ene(1b), (2S, 3S, 4R, 8E) -2-[(2'R) -2'-hydroxy-heneicosanoylamino]-heneicosane-1,3,4-triol-8-ene (1c), (2S, 3S,4R, 8E)-2-[(2'R) -2'-hydroxy-docosanoylamino] -eicosane-1,3,4-triol-8-ene (1d), (2S, 3S, 4R, 8E)-2-[(2'R)-2'-hydroxy-trico-sanoylamino]-nonadecane-1,3,4-triol-8-ene (1e), (2S,3S,4R,8E)-2-[(2'R)-2'-hydroxy-lignocera-noylamino]-cctadecane-1,3,4-tri-ol-8-ene(1f), 1-O-beta-D-glucopyranosyl-(2S, 3S, 4R, 8E)-2-[(2'R)-2'-hydroxy-pentadecanoylamino]-nonadecane-1, 3, 4-triol-8-ene (2), 16alpha-hydroxy-ent-kauran-19-ocid (3), 16alphaH, 17-isovaleryloxy-ent-kauran-19-oic acid (4), coniferin (5), syringin (6), eleutheroside D (7), stigmasterol (8), beta-sitosterol (9), daucosterol (10), pentacosanoic acid (11).
  
  
  CONCLUSIONS
  Compounds 1a - f, 2 are isolated from this genus for the first time, and compounds 4, 5, 11 are firstly obtained from Acanthopanax gracilistylus.
