title: [Studies on the new triterpenoid saponin of the aerial part of Cimicifuga foetida].
abstract: OBJECTIVE
  To find new active constituents from the aerial part of Cimicifuga foetida.
  
  
  METHODS
  Various column chromatographic techniques were used for the isolation and purification of the principles. The structures were elucidated on the basis of spectral data and chemical evidences.
  
  
  RESULTS
  Four 9,19-cycloartane triterpenoid saponins were obtained and identified as Cimifoetiside III (25-anhydrocimigenol-3-O-beta-D-galactopyranoside, 1), 25-O-acetyl-cimigenol xylopyranoside (2), 25-O-acetyl-cimigenol galactopyranoside (3), 7 beta-hydrocimigenol xylopyranoside (4).
  
  
  CONCLUSIONS
  Compound 1 is new and compound 4 was isolated from this plant for the first time.
