title: [Studies on the chemical constituents in roots of Angelica tianmuensis and A. megaphylla].
abstract: OBJECTIVE
  To study the chemical constituents in roots of Angelica tianmuensis and A. megaphylla.
  
  
  METHODS
  Compounds were isolated by column chromatography with silica gel, their structures were identified by spectral analysis.
  
  
  RESULTS
  Another three compounds (ligustilone, 5-methoxyhamaudol, cimifugin) were obtained from the roots of Angelica tianmuensis, and another two compounds (ligustilone, angelol) were obtained from the roots of A. megaphylla.
  
  
  CONCLUSIONS
  All the compounds are isolated in these two plants for the first time, and ligustilone is first found from Angelica L..
