title: [Cycloartane triterpenes and glycosides from Cimicifuga acerina].
abstract: OBJECTIVE
  To investigate the chemical constituents from the rhizomes of Cimicifuga acerina (Sieb. et Zucc.) Tanaka.
  
  
  METHODS
  Column chromatgraphy (including silica gel and ODS) together with HPLC was used to separate the chemical constituents whose structures were determined by FAB-MS, NMR (1D and 2D) and hydrolysis methods.
  
  
  RESULTS
  Five cycloartane triterpenoids were isolated and identified as: (22R)-22-hydroxycimigenol (I), (22R)-22-hydroxy-24-O-acetylhydroshengmanol 3-O-beta-D-xylopyranoside (II), dahurinol (III), 24-epi-24-O-acetyl-7,8-didehydroshengmanol 3-O-beta-D-xylopyranoside (IV), 25-O-acetyl-7,8-didehydrocimigenol 3-O-beta-D-xylopyranoside (V).
  
  
  CONCLUSIONS
  Compound I is a new natural product, compound II is a new compound and compounds IV and V were isolated from this plant for the first time.
