title: [Studies on chemical constituents in stems of Zanthoxylum dissitum].
abstract: OBJECTIVE
  To study the chemical constituents from the stems of Zanthoxylum dissitum.
  
  
  METHODS
  Column chromatography on macroporous resin and silica gel, and spectral analysis were used to isolate and elucidate the constituents.
  
  
  RESULTS
  Seven compounds were isolated and identified as 5,8-dimethoxyethane-3,4-epoxy-furanocoumarin (1), isoimpinellin (2), beta-sitosterol (3), lupeol (4), neohesperidin (5), beta-daucosterol (6), ursolic acid (7).
  
  
  CONCLUSIONS
  All above the compounds were isolated from the plant for the first time and the compound 1 is a new compound.
