title: [Studies on the chemical constituents in herb of Ranunculus japonicus].
abstract: OBJECTIVE
  To isolate and determine the chemical constituents from Ranunculus japonicus.
  
  
  METHODS
  Compounds were isolated by column chromatography, and identified by MS, NMR data.
  
  
  RESULTS
  Nine compounds were obtained andelucidated as scoparone (1), tricin (2), protocatechuic acid (3), luteolin (4), anemonin (5), scopoletin (6), 5-hydroxy-6, 7-dimethoxyflavone (7), 5-hydroxy-7, 8-dimethoxyflavone (8), ternatolide (9), respectively.
  
  
  CONCLUSIONS
  Compounds 1-9 were isolated from R. japonicus for the first time while compounds 7, 8 were separated from Ranunculus genus first time.
