| Abstract: | The volatile components in the needle and branch of Picea crassifolia. were extracted by solid phase micro extraction (SPME) and were analyzed by GC MS. About 65 different compounds were identified. Forty two were found in the needle, accounting for 99.78 % the total area, including α pinene, camphene, acetate of (1S endo) 1,7,7 trimethyl cyclo［2.2.1］heptan 2 ol. Fifty were found in the branch, accounting for 99.93 % of the total area, including à Pinene, α phellandrene, camphene, (R) 1 methyl 5 (1 methylethenyl) cyclohexene, caryophyllene. The content terpenes were the main components in the volatiles. |
