abstract: OBJECTIVE
  To study the chemical constituents of sini tang.
  
  
  METHODS
  The constituents were separated by means of column chromatography and their structures were identified by spectral data and compared with literature data.
  
  
  RESULTS
  Six compounds were isolated and identified as vanillic acid, formononetin, isoliquiritigenin, liquiritigenin, kumatakenin B and uracil.
