title: [Studies on chemical constituents of Ligustrum obtusifolium Sieb. et Zucc].
abstract: OBJECTIVE
  To study the chemical constituents in the twigs and leaves of Ligustrum obtusifolium.
  
  
  METHODS
  Seven compounds were isolated from the ethanol extract of the twigs and leaves by polystyrene resin RA and silica gel column chromatography. The structures were identified by spectral analysis.
  
  
  RESULTS
  Of the seven compounds isolated six were identified as luteolin, luteolin-4'-O-beta-D-glucopyranoside, (+)-pinoresinol, (+)-pinoresinol-4'-O-beta-D-glucopyranoside, (+)-medioresinol and (-)-olivil.
  
  
  CONCLUSIONS
  luteolin, luteolin-4'-O-beta-D-glucopyranoside, (+)-pinoresinol, (+)-medioresionnol and (-)-olivil were isolated from this plant for the first time.
