title: [Studies on constituents from Taxus mairei Bark].
abstract: OBJECTIVE
  To find the active constituents from Taxus chinensis var. mairei.
  
  
  METHODS
  The constituents were isolated and purified by supercritical carbon dioxide extraction and column chromatography. Their structures were determined primarily in the basis of their 1H-NMR, 13C-NMR and DEPT, MS, IR.
  
  
  CONCLUSIONS
  Three compounds were isolated from Taxus mairei and identified as taxinine E, taxol and baccatin III. Taxinine E and baccatin III were found from Taxus chinensis var. mairei for the first time.
