The invention relates to a preparation method of a tobacco extract based on a catalytic selective oxidation technology. The preparation method comprises the following steps: selecting set tobacco raw materials and putting the selected tobacco raw materials in a sealed reaction container; adding a set amount of solvent and catalyst into the sealed reaction container, and filling oxygen-containing gas into the sealed reaction container to a set pressure; and heating the reaction container, continuously stirring for a set time, and after the reaction is finished, separating a liquid part to obtain the tobacco extract. According to the technical scheme, the degree of oxidation reaction of the target component in the tobacco raw material and the selectivity of the product can be effectively controlled by changing the catalytic system, so that the aroma characteristics of the tobacco extract are regulated and controlled, and controllable aroma production is realized. When the tobacco extract is used for tobacco per
