title: [The megastigman glycosides from herb of Potentilla multifida].
abstract: OBJECTIVE
  To investigate the chemical constituents of Potentilla multifida.
  
  
  METHODS
  Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by spectral analysis.
  
  
  RESULTS
  Four megastigmane glycosides were isolated from P. multifida and their structures were identified as citroside A (1), icariside B1 (2), (6S,7E,9R)-roseoside (3), (6S,7E,9R)-vomifoliol-9-O-beta-D-xylopyranosyl-(1-->6)-O-beta-D-glucopyranoside (4), respectively.
  
  
  CONCLUSIONS
  All compounds were obtained from the genus Potentilla for the first time.
