title: [Studies on chemical constituents from roots of Angelica polymorpha].
abstract: OBJECTIVE
  To investigate the chemical constituents of the roots of Angelica polymorpha.
  
  
  METHODS
  Silica gel column chromatography was employed for the isolation and purification of chemical constituents. The structures were identified on the basis of spectral data and chemical evidence.
  
  
  RESULTS
  Fourteen compounds were isolated and identified as follows, 5-hydroxy-2-[(angeloyloxy) methyl] furan [3', 2': 6, 7] chromone (1), octacosanoic acid (2), isoimperatorin (3), 3'S-(-)-O-acetylhamaudol (4), bergapten (5), iso-oxypeucedanin (6), beta-sitosterol (7), angeliticin A (8) , saxalin (9), pabulenol (10), noreugenin (11), oxypeucedanin hydrate (12), daucosterol (13), sucrose (14).
  
  
  CONCLUSIONS
  Compound 1 is a new chromone, named polymorchromone A. Compounds 2, 4, 11, 13, 14 were isolated from A. polymorpha for the first time.
