[Study on the volatile oil of Murraya exotica].
OBJECTIVE
To study the volatile oil of Murraya exotica.


METHODS
The volatile oil of Murraya exotica was extracted by steam-stilling and was identified by GC-MS-DS.


RESULTS
More than 90 compounds were separated, and 59 compounds were identified, accounting for 93.9% of the total essential oil of Murraya exotica. The major constituents of volatile oil were bicyclogermacrene (26.0%), beta-caryophyllene (20.8%), alpha-caryophyllene (5.8%), delta-cadinene (4.7%), spathulenol (4.3%), trans-alpha-bergamotene (4.1%), germacrene D (3.7%), beta-bisabolene (3.0%), ar-Curcumene (2.5%).


CONCLUSIONS
The major components of Murraya exotica are the terpenoids, including 80.6% of sesquiterpenoids and 11.9% of monoterpenoids. Bicyclogermacrene is identified in Murraya genus for the first time.
