title: [Studies on hydrolysable tannin constituents in seed of Juglans regia(I)].
abstract: OBJECTIVE
  To study hydrolysable tannin constituents of the seeds of Juglans regia.
  
  
  METHODS
  The chemical constituents were isolated by Diaion HP-20 and Toyopaerl HW-40 MCI gel CHP-20P column chromatogramphy and identified by physicochemical identification and spectral data.
  
  
  RESULTS
  The compounds obtained from the 70% acetone extract were identified as gemin D (1), casuariin (2), pedunculagin (3), tellimagrandin I (4), rugosin F (5), heterophylliin D (6).
  
  
  CONCLUSIONS
  All other compounds which were isolated from the seeds of J. regia for the first time.
