Abstract:

To provide the foundation for reasonable utilization by analyzing the contents and components of volatile oils from the leaf of Syzygium grijsii in different areas. The volatile oils were extracted by steam distillation and studied by means of the GC/MS/DS, the components were quantitatively determined with area normalization method.The results showed that the major components were sesquiterpenoid and terpenol of the volatile oils. 35 components were identified of the volatile oil from Minhou,Fujian Province. It was composed of 84.09% of total volatile oils. The main components were β-Cubebene(16.31%),β-Cadinene(10.78%),Elixene(8.36%),τ-Cadinene(5.23%).32 components were identified of the volatile oil from Changting,Fujian.It was composed of 72.08% of total volatile oils.The main components were Spathulenol(11.29%),β-Selinene(8.72%),τ- Cadinene(8.23%),τ-Muurolene(6.68%),Aromadendrene(6.24%),α-Gurjunene(5.58%). There was few difference among the components but significant differences among the contents of volatile oils of Syzygium grijsii from Minhou and Changting,Fujian Province.

Key words: Syzygium grijsii, volatile oil, chemical component
