The application discloses a plant seed dry distillation refined product and a preparation method and application thereof. The dry distillation refined product is obtained by the following steps: carrying out dry distillation reaction on plant seeds to obtain a dry distillation seed raw material; uniformly mixing the dry distillation seed raw material with a solvent and then carrying out homogenization treatment, and then carrying out solid-liquid separation, collecting supernatant, and obtaining a dry distillation seed raw material extract; and carrying out molecular distillation on the dry distillation seed raw material extract and collecting a light component fraction. The dry distillation refined product takes cocoa beans or coffee beans as raw materials, greatly improves the content and types of aroma substances based on the synergistic effect between steps, especially the flavor characteristics of cocoa or coffee itself, and is applied to a heat-not-burn cigarette as a tobacco flavor, so that the heat-not-burn cigarette can release a flavor with obvious cocoa aroma or coffee aroma characteristics, and also has rich and mellow burnt aroma, and the richness and thickness of the aroma are greatly improved.
