title: [Stuides on evaluation of Semen Armeniacae amarum].
abstract: OBJECTIVE
  To systematically evaluate the quality of Semen Armeniacae Amarum.
  
  
  METHODS
  The amygdalin content in the samples of Semen Armeniacae Amarum from different markets was analysed by HPLC. Some physical and chemical tests were done to investigate their quality.
  
  
  RESULTS
  Some significant differences in amygdalin contents and some physical and chemical parameters were shown between the crude drugs and the processed ones. There are few changes in amygdalin contents with the storage in 17 years.
  
  
  CONCLUSIONS
  The processing conditions are the main factors that affect the quality of Semen Armeniacae Amarum. Furthermore, a systematic evaluation of the quality of its samples from the different markets has been established by a radar diagram based on the following five parameters: amygdalin contents, the lipid content, ethanol-soluble extract, total ash and acid-insoluble ash.
