title: [Studies on extraction and purification of active parts of ferulic acid from Ligusticun chuanxiong].
abstract: OBJECTIVE
  To study on the process of extraction and purification of active parts from Ligusticun chuanxiong.
  
  
  METHODS
  The processes of extraction and purification of active parts of ferulic acid were optimized by direct comparison and orthogonal design.
  
  
  RESULTS
  Extract rate of active parts of ferulic acid was 1.67% and the content of ferulic acid was 5.82%.
  
  
  CONCLUSIONS
  Active parts of ferulic acid from L. chuanxiong were extracted and purified effectively.
