Abstract: In order to compare the components in different positions of Elsholtzia, and the influence of the volatile oils to the sense quality of tobacco. The Gas chromatography-mass spectrum instrument was used to analyze the volatiles of various stalk position of Elsholtzia, which were extracted by simultaneous distillation and solvent extraction (SDE). The major components included Elsholtzia ketone and Dehydroelsholtzia ketone by area normalization method. The relative contents of Flower、stems and leaves are 19.93%,57.19%;20.39%, 50.31%;18.02%,44.68% respectively. The volatile oils were used in the tobacco which can improve the smooth and show the delicate green note.
