Objective: To study the chemical constituents of the volatile oil from the rhizome of Anemarrhena asphodeloides.
Method: 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.
Result: 24 volatile compounds were isolated and identified for the first time, representing 70.83% of the total oil.
Conclusion: 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%).
