| description | The invention discloses a method for extracting a tobacco aroma raw material by using an ionic liquid as an extracting agent. The method comprises the following steps: crushing and sieving a tobacco raw material to obtain tobacco powder; the method comprises the following steps: mixing tobacco powder and ionic liquid according to a set mass ratio, sealing, carrying out ionic liquid extraction on the tobacco powder, cooling to room temperature, carrying out reverse extraction by using an organic solvent, carrying out centrifugal separation on the tobacco powder and the organic solvent, collecting supernate, and carrying out reduced pressure distillation to remove the organic solvent, so as to obtain the tobacco aroma raw material. The ionic liquid is composed of cations and anions, and the cations are selected from at least one of imidazole cations, pyridine cations, choline cations, piperidine cations, pyrrolidine cations and choline cations without substituent groups or with substituent groups.
