title: [Analysis of fatty acids in the seeds of Sterculia lychnophora by GC-MS].
abstract: OBJECTIVE
  To analyze and identify fatty acids in the seeds of Sterculia lychnophora.
  
  
  METHODS
  The compositions was isolated and determined by GC-MS technique, and area normalization method was used to make quantitative analyze of the content of compositions.
  
  
  RESULTS
  21 Fatty acids and 5 other compositions were isolated and determined.
  
  
  CONCLUSIONS
  The major fatty acids are 9,12(Z,Z)-octadecadienoic acid(37.96%), hexadecanoic acid(24.77%), 9-(Z)-octadecenoic acid(19.77%) and octadecanoic acid(5.01%).
