title: [Preparation of forsythiaside from Forsythia suspensa by high-performance liquid chromato- graphy].
abstract: OBJECTIVE
  To prepare forsythiaside from Forsythia suspensa by high-performance liquid chromatography (HPLC).
  
  
  METHODS
  A crude extract of Forsythia suspensa was prepared by water extraction and alcohol precipitation prior to polyamide column chromatography. Forsythiaside was prepared from the crude extract by RP-HPLC.
  
  
  RESULTS
  Analysis with HPLC showed that the purity of the prepared forsythiaside reached 98%.
  
  
  CONCLUSIONS
  HPLC is simple and effective for the preparation of forsythiaside from Forsythia suspensa.
