title: [Isolation and structural identification of phenylethanoid glycosides from Corallodiscus flabellata].
abstract: OBJECTIVE
  To study the chemical constituents from Corallodiscus flabellata.
  
  
  METHODS
  The compounds were isolated and purified by macroporous adsorption resin, silica gel column chromatography and identified on the basis of their physiochemical and spectral data.
  
  
  RESULTS
  Three phenylethanoid glycosides (I-III) were obtained from the n-BuOH fraction of water-extracts. Their structures were elucidated as 3,4-dihydroxyphenylethanol-8-O-[beta-D-apiofuranosyl (1-->3)]-beta-D-glucopyranoside (I), 3,4-dihydroxyphenylethanol-8-O-[4-O-trans-caffeoyl-beta-D-apiofuranosyl (1-->3)-beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside (II) and 3,4-dihydroxyphenylethanol-8-O-[beta-D-apiofuranosyl(1-->3)-beta- D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside (III).
  
  
  CONCLUSIONS
  Compounds I, II and III are new compounds.
