Objective: To analyze and compare the volatile constituents which were extracted from the different parts of Betula luminifera by GC-MS. Method: The volatile components were extracted from the different parts of B. luminifera by t MAE-HS-SPME and the chemical components of them were identified by GC-MS and retention index. Result: 58 and 25 volatile constituents in the leaf and fruits of Betula luminifera were separated and identified. Accounting for 95.78% and 95.72% of the total peak areas

respectively. The major components in the leaf oil were pentadecane (5.50%)

hexadecane (6.54%)

(E)-1

2

3-trimethyl-4-propenyl- naphthaleene(5.13%)

whereas the major constituents in the fruit oil were cis-β-farnesene (10.04%)

β-bisabolene(24.81%)

α-caryophyllene (25.61%) and α-bisabolol(16.42%). Conclusion: The results show that the two parts of the volatile components are quite different.
