title: [Analysis of volatile constituents from Anemarrhena asphodeloides by GC-MS].
abstract: OBJECTIVE
  To study the chemical constituents of the volatile oil from the rhizome of Anemarrhena asphodeloides.
  
  
  METHODS
  The volatile oil was steam distillation. Chemical constituents were separated and analyzed by GC-MS. The relative content of each component was determined by area nomalization.
  
  
  RESULTS
  24 volatile compounds were isolated and identified for the first time, representing 70.83% of the total oil.
  
  
  CONCLUSIONS
  The main constituents of this oil were aldehydes (31.15%), terpene and their oxide (20.66%), alkyls (8.35%), Furan heterocyclic compounds (6.41%), non terpene alcohol (4.26%). There are 12 compounds with contents over 3%. Among them, borneol has the highest content (9.35%).
