title: [Studies on the coumarins in the root of Zanthoxylum dimorphophyllum].
abstract: OBJECTIVE
  To study the chemical constituents of the dried roots of Zanthoxylum dimorphophyllumr. spinifolium and to find out the active constituents of the plant.
  
  
  METHODS
  Modern chromatography was used to purify chemical constituents, and their structures were identified by various spectral methods.
  
  
  RESULTS
  Four compounds were isolated and identified as isopimpinellin (I), xanthoxyletin (II), 6-(2', 3'-dihydroxy-3'-methyl-butyl)-7-hydroxy-2H-1-benzopyran-2-one (III), 6-(2'-O-beta-D-glucopyranosyloxy, 3'-dihydroxy-3'-methybutyl)-7-hydroxy-2H-1-benzopyran-2-one (IV).
  
  
  CONCLUSIONS
  All of the above compounds were isolated from the above mentioned plant for the first time.
