title: [Gas chromatography-mass spectrometric analysis of Jatropha curcas leaf extracts prepared by supercritical fluid CO2 extraction].
abstract: OBJECTIVE
  To analyze the bioactive components in Jatropha curcas leaves using gas chromatography-mass spectrometry (GC-MS).
  
  
  METHODS
  The bioactive components were extracted from J. curcas leaves by supercritical fluid CO2 extraction and analyzed by using GC-MS.
  
  
  RESULTS
  Seventy peaks were detected by GC-MS, and 43 compounds were identified (61.43%). Among the identified compounds, 16 had a content of more than 1%, and the total contents of these 16 compounds reached 81.36%. The four most abundant components were 22,23-dihydro-stigmasterol (16.14%), alpha-tocopherol (15.18%), beta-amylin (7.73%) and dotriacontanol (7.02%). The content of gamma-tocopherol reached 2.88% and vitamin E reached 18.06% in the extract.
  
  
  CONCLUSIONS
  J. curcas leaves contain multiple compounds with anti-tumor, anti-virus and antimicrobial activities.
