title: [Chemical constituents from Speranskia tuberculata (Bge.) Baill].
abstract: OBJECTIVE
  To investigate the chemical constituents from the herb Speranskia tuberculata.
  
  
  METHODS
  The chemical constituents were extracted with solvent and separated with column chromatography. The structures were elucidated by spectral analysis.
  
  
  RESULTS
  Two compounds were isolated from the plant and identified as 18-hydroxy(-)-manool and beta-sitosterol.
  
  
  CONCLUSIONS
  Both were separated from this plant first time.
