Feature in the tobacco lobe where the fragrance type which this invention offers differs to be fragrant, the super critical selection manner of the material, (1) to cut the tobacco lobe, to disconnect in the tobacco, step and (2) it leaves in the super critical CO₂ fluid extraction tank 100 - 350bar, to designate selection temperature as 35 - the 70, to cut the selection pressure of the super critical CO₂ fluid under this condition, after executing the quiet voice selection 10 - 35min vis-a-vis the tobacco, the step which executes the movement selection 5 - 15min it cuts the movement selection velocity of flow of super criticality CO₂ as 1.0 - 3.5L/min, vis-a-vis the tobacco(3) to collect the super critical CO₂ fluid extract which is acquired, after CO₂ volatilizing completely, it includes with the step which obtains the principal fragrance incitement material which decides the fragrance type of tobacco lobe.
