[Analysis of volatile oil from different parts of Litsea cubeba]

To analyze and compare the compounds of the essential oil from the fruits and leaves and roots of Litsea cubeba.

With steam distillation extraction method, Litsea cubeba essential oil was extracted from the fruits and leaves and roots. The qualitative and quantitative analysis of Litsea cubeba essential oil were carried out with GC-MS.

18 compounds were identified from the fruits (93.57% of the total essential oil) and 17 compounds were identified from the roots (98.01% of the total essential oil) and 28 compounds were identified from the leaves (95.33% of the total essential oil). The main constituents of the fruits essential oil were Citral, Limonene, and so on; The main constituents of the roots essential oil were Citral, 6-Octenal, 3,7-dimethyl-, 2-Octen-1-ol, 3,7-dimethyl-, and so on; The main constituents of the leaves essential oil were Citral, Eucalyptol, Citronellol, 6-Octenal, 3,7-dimethyl-, and so on.

The constituents of volatile oil extracted from the different parts of Litsea cubeba were different, so they should be utilized differently in clinical application and study in great depth.
