title: [Chemical constituents from Ajuga nipponensis].
abstract: OBJECTIVE
  To study the chemical constituents of Ajuga nipponensis.
  
  
  METHODS
  The chemical constituents were isolated by repeated silica gel column chromatography and their structures were elucidated by phyisochemical properties and spectral analysis.
  
  
  RESULTS
  Ten compounds were isolated and identified as:hexadecanoic acid(1), ajuforrestin A(2), beta-sitosterol(3), acacetin(4), apigenin(5), ajugamacrin B(6), ursolic acid(7), beta-ecdysone(8), 8-acetylharpagide(9) and daucosterol(10).
  
  
  CONCLUSIONS
  Compounds 1-7 and 10 are isolated from this plant for the first time.
