Abstract: The essential oils from Baccaurea ramiflora Lour. root, leaf and fruit were extracted and their chemical constituents were analyzed by GC-MS for the first time. Totally 37 compounds in the Baccaurea ramiflora Lour. root essential oils were extracted and 34 of them were identified, which accounted for over 98.46% of the essential oils. The results showed that 10 compounds of essential oils from leaves and roots of Baccaurea ramiflora Lour. are the same, whose relative contents are 76.66%. 7 compounds of essential oils from fruits and roots of Baccaurea ramiflora Lour. are the same, whose relative contents are 69.82%. The study offers theoretic base for utilization of Baccaurea ramiflora Lour root, leaf and root.
