title: [Lignans from Stem Bark of Styrax perkinsiae].
abstract: OBJECTIVE
  To study the chemical constituents in the stem bark of Styrax perkinsiae.
  
  
  METHODS
  The chemical constituents were separated and purified by chromatographic methods after solvent extraction and identified by spectroscopic analyses.
  
  
  RESULTS
  Ten lignans were isolated from the stem bark of Styrax perkinsiae and identified as following: pinoresinol 4-O-β-D-glucopyranoside (1), matairesinoside (2), styraxlignolide B (3), 3- (β-D-glucopyranosyloxymethyl)-2-(4-hydroxy-3-methoxyphenyl)-5-(3-hydroxypropyl )-7-methoxy-(2R , 3S) -dihydrobenzofuran (4), burselignan (5), (+) -neo-olivil (6), threo-1-(4-hydroxy-3-methoxyphenyl )-2-[ 4-(3-hydroxypropyl)-2-methoxyphenoxy]-1, 3-propanediol (7), erythro-1-(4-hydroxy-3-methoxyphenyl )-2-[ 4-(3-hydroxypropyl )-2-methoxyphenoxy ] -1 ,3-propanediol (8), isolariciresinol(9) and (+) -lariciresinol (10).
  
  
  CONCLUSIONS
  Compounds 5 - 10 are isolated from the plants of Styrax genus for the first time.
