title: [Non-taxoid chemical constituents from leaves of Taxus mairei].
abstract: OBJECTIVE
  To study the non-taxoids in the leaves of Taxus mairei.
  
  
  METHODS
  The chemical constituents were isolated by chromatography and identified by spectral data.
  
  
  RESULTS
  Five compounds, taxamairin A (1), taxamairin B (2), sciadopitysin (3), ( - ) matairesinol (4), ponasterone A (5) were isolated and identified.
  
  
  CONCLUSIONS
  Compounds 3-5 were isolated from this plant for the first time, compounds 1 and 2 were isolated from the leaves of T. mairei for the first time.
