title: [Study on spaceflight mutagenesis Platycodon grandiflorum via FTIR].
abstract: OBJECTIVE
  To establish a method for analyzing amorphous organic compound components of space Platycodon grandflorum rapidly.
  
  
  METHODS
  FTIR was applied for measuring and comparing P. grandflorum of comparison group,the ground group and the 4" generation of space group.
  
  
  RESULTS
  Several active components (platycodin, polysaccharide etc.) contents of space group are increased obviously.
  
  
  CONCLUSIONS
  The major components and the structures remained inextenso,and the effictive component contents are enhanced in the space P. grandiflorum. FTIR is a fast method to analyze the changes of amorphous organic compound components of the space traditional Chinese medicines.
