title: [Chromatographic identification of a compound similar to ferulic acid in the decoction of Herb Leonuri].
abstract: OBJECTIVE
  To identify whether there is ferulic acid in decoction of Herb Leonuri.
  
  
  METHODS
  By TLC and HPLC.
  
  
  RESULTS
  The chromatogram of the sample showed a dark brown fluorescent spot at the same Rf value of ferulic acid in TLC identification test. The retention time of a peak in the HPLC of the sample corresponded to that of ferulic acid.
  
  
  CONCLUSIONS
  There is a compound which is very similar to ferulic acid in the decoction of Herb Leonuri.
