title: [Chemical constituents of pattra medicine Euodia lepta].
abstract: OBJECTIVE
  To study the chemical constituents of Pattra Medicine Euodia lepta in Xishuangbanna of Yunnan Province.
  
  
  METHODS
  The chemical constituents were isolated and purified by chromatographic techniques, and identified by NMR, MS and other spectral methods.
  
  
  RESULTS
  In 60% ethanol extract from the stems,and 95% ethanol extract from the leaves, six compounds and two compounds were isolated and identified as pachypodol( 1) ,3-(3-methyl-but-2-enyl )umbelliferone(2),7-demethylsuberosin (3),beta-sitosterol (4),3,7-dimethoxy kaempferol(5), euolitrine(6), sesamin(7) and p-O-geranyl coumaric acid(8), respectively.
  
  
  CONCLUSIONS
  Compound 7 is obtained from Euodia genus for the first time,and compound 8 is obtained from domestic Euodia lepta for the first time.
