title: [Saponins from roots of Stephanotis mucronata].
abstract: OBJECTIVE
  To study the chemical constituents from n-BuOH fraction of the roots of Stephanotis mucronata.
  
  
  METHODS
  The compounds were separated by chromatographic methods. A combination of UV, MS, and NMR spectroscopic methods was applied to identify structure of these compounds.
  
  
  RESULTS
  Four oleane saponins were isolated and identified as sitakisoside VII (1), sitakisoside VI (2), sitakisoside II (3), and sitakisoside I (4).
  
  
  CONCLUSIONS
  These four compounds were obtained for the first time from this plant.
