title: [Study on volatile components from flowers of Gymnema sylvestre].
abstract: OBJECTIVE
  To analyze the volatile components from flowers of Gymnema sylvestre.
  
  
  METHODS
  Volatile components of flowers of Gymnema sylvestre were extracted by water vapor distilling, and the components were separated and identified by GC-MS.
  
  
  RESULTS
  55 components were separated and 33 components were identified, accounting for 88.73% of all quantity. The principal volatile components are Phytol, Pentacosane, 10-Heneicosene (c, t), 3-Eicosene, (E) -and 2-Methyl-Z-2-docosane.
  
  
  CONCLUSIONS
  The research can pro-vide scientific basis for chemical component research of flowers of Gymnema sylvestre.
