title: [Comparative Study on Volatile Constituents of Plumeriae Flos from Different Origins].
abstract: OBJECTIVE
  To compare the volatile constituents of Plumeriae Flos from different origins.
  
  
  METHODS
  Water distillation method according to the Chinese Pharmacopeia was used to extract the volatile constituents of fresh Plumeriae Flos samples (red flower and white flower) and dried samples. GC-MS method combined with NIST MS Search 2.0 data base was carried out to identify the volatile constituents and to calculate the relative percentage content.
  
  
  RESULTS
  55 peaks were detected in the GC-MS spectrum. Among of them, 26 volatile constituents were confirmed and calculated, which were mainly fatty alcohols and esters. The relative percentage content of geranyl benzoate in fresh Plumeriae Flos samples was significantly higher than the dried samples.
  
  
  CONCLUSIONS
  The compositions of volatile constituents in Plumeriae Flos have no obvious correlation with the color of flowers, but are related to the flower fresh or dried.
