title: [Studies on the chemical constituents from the aerial parts of Cimicifuga dahurica].
abstract: OBJECTIVE
  To seek for new bioactive constituents from the aerial parts of Cimicifuga dahurica.
  
  
  METHODS
  Various column chromatographic techniques were employed for the isolation and purification of the ingredients. The structures were elucidated on the basis of 1H, 13CNMR, 1H-1H COSY, HMQC, NOESY and HMBC spectra and chemical reactions.
  
  
  RESULTS
  Two cyclolanostanol xylosides, cimidahuside C and D were isolated from the EtOAc section of EtOH extracts.
  
  
  CONCLUSIONS
  Cimidahuside C(1) and D(2) are new triterpenoid xylosides.
