title: Essential oil composition analysis of three cultivars seeds of Resina ferulae from Xinjiang, China.
abstract: OBJECTIVE
  Three cultivars seeds of Resina ferulae were analyzed for essential oil composition, Ferula sinkiangensis K. M. Shen, Ferula fukangensis K. M. Shen, and Ferula ovina, investigated differences among different genera of medicinal R. ferulae.
  
  
  METHODS
  The essential oils were extracted by the method of hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS), using normalization method to calculate relative amount.
  
  
  RESULTS
  Twenty-six compounds were identified in F. sinkiangensis K. M. Shen, comprised 99.001% of total essential oil; 21 compounds were identified in F. fukangensis K. M. Shen, comprised 100% of total essential oil; 25 compounds were identified in F. ovina, comprised 99.459% of total essential oil. n-Propyl sec-butyl disulfide is the main component in three cultivars seeds of R. ferulae, accounting for 55.875%, 49.797%, 53.781%, respectively.
  
  
  CONCLUSIONS
  Little diversity among three cultivars seeds of R. ferulae from Xinjiang.
