title: [Chemical Constitutes from Root of Artocarpus styracifolius].
abstract: OBJECTIVE
  To study the chemical constituents from root of Artocarpus styracifolius.
  
  
  METHODS
  Tne constituents were isolated from the root of Artocarpus styracifolius by column chromatography over silica gel, RP-18 silica gel, MCI GEL CHP-20P, macroporous resin HP-20, Sephadex LH-20, Toyopearl HW-40C and by preparative HPLC. Their structures were elucidated by analysis of physical and chemical properties and spectral data.
  
  
  RESULTS
  Nine compounds were isolated and their structures were identified as p-hydroxy benzoic acid (1), syringic acid (2), 2,4-dihydroxy benzaldehyde (3), (+)-lyoniresinol (4), 5,5'-dimethoxysecoisolariciresinol (5), (+)- syringaresinol (6), scopoletin (7), xylarolide (8) and trans-oxyresveratrol (9).
  
  
  CONCLUSIONS
  Compounds 2, 5, 6 and 8 are isolated from Moraceae for the first time. Compounds 1, 4 and 7 are firstly characterized in the genus Artocarpus, compounds 3 and 9 are characterized in Artocarpus styracifolius for the first time.
