The volatile from pine needles of Pinus yunnanensis was extracted by steam distillation. The chemical constituents of the volatile were analyzed by GC-MS and their rative contents was determined by area normalization. 53 compounds were separated,50 of them were identified.These 50 compounds amounted totally to about 94% of the components in the volatile and 97.467% of the total peak area. The maior components of the volatile were palmitamide(16.581%)and germacrene D(15.045%).
