The invention provides a preparation method for plum spice used for cigarette. The method comprises the steps that after being washed and airdried, plum fruits are dried; after smashing is conducted, plum coarse powder is obtained through ten-mesh sieve; after reflux extraction is conducted by using water, filter liquor is obtained by filtering, and a plum coarse extracting solution is obtained; after the plum coarse extracting solution is cooled down to indoor temperature, subtilisin is added, and plum enzymolysis liquid is obtained through enzymolysis; ethanol is added, and plum sedimentation liquid is obtained by stirring and sedimenting; after filtering is conducted, concentration is conducted, and n-butanol extract liquor is obtained through extraction after water and n-butanol are added; the plum spice used for the cigarette is obtained by adding propylene glycol after concentration is conducted. The plum spice is obtained by using the plum fruits, the utilization rate of a plum is improved, by means of the preparation method, environmental protection is achieved, the solvent can be reused, and the cost is lowered. At the same time, the perfume of the plum spice used for the cigarette prepared by using the method is intense and lifelike, the aroma quality of the cigarette can be improved obviously, the functions of softening of smoke, strengthening of oral sweet feeling and improving of sending performance of the smoke are achieved, and the practicality is strong.
