title: [Analysis of non-alkaloids from radix sophorae tonkinensis by GC-MS].
abstract: OBJECTIVE
  To analyze the chemical compositions and their contents in non-alkaloids fraction from Radix Sophorae Tonkinensis.
  
  
  METHODS
  The non-alkaloids from Radix Sophorae Tonkinensis were analyzed by gas chromatography/mass spectrometry after trimethylsilyl derivatization. The chemical compositions were identified by comparison of the authentic sample and NIST database; the contents of 19 identified components were determined by linear regression equation.
  
  
  RESULTS
  19 compounds constituting 34.72% of the non-alkaloids were identified. The major components were saccharides (5 compounds constituting 22.62%), organic acid (9 compounds constituting 11.81%), and others (5 compounds constituting 0.29%).
  
  
  CONCLUSIONS
  The GC-MS is a simple, rapid and sensitive method to investigate the complex primary metabolites in plants.
