title: [Studies on the chemical constituents in herb of Ranunculus sceleratus].
abstract: OBJECTIVE
  To isolate and determine the chemical constituents from Ranunculus sceleratus.
  
  
  METHODS
  Six compounds were isolated and purified by extraction and different kinds of column chromatography. The structures were determined on the basis of extensive spectral analysis such as EI-MS, 1H-NMR, 13C-NMR, DEPT and NOEDS.
  
  
  RESULTS
  The structures were elucidated as stigmasta-4-ene-3,6-dione I, stigmasterol II, isoscopoletin III, scoparone IV, protocatechuic aldehyde V and protocatechuic acid VI, respectively.
  
  
  CONCLUSIONS
  Compound I, III, IV, V and VI were isolated from R. genus for the first time.
