  • Cembranoids are a group of natural diterpenoid compounds with a characteristic 14-membered ring structure, and are widely distributed in nature. To date, many cembranoids have been reported from plants (conifers, tobacco), insects, and marine organisms. In recent years, they have attracted great interest from researchers of natural products and pharmaceuticals due to their attractive structures and biological activities such as antibacterial, anticancer, and anti-inflammatory effects. Nicotiana species are the terrestrial plant that contains the most cembranoids, which contribute to the characteristic aroma of tobacco.
  • cembratrienediol in tobacco is said to bind to nicotinic acetylcholine receptors (nAChR) and have neuroprotective and anti-nicotine addiction effects, suggesting that tobacco contains physiologically active substances with both addictive and anti-addictive properties derived from nicotine.

It is said that the addition of solanone to tobacco enhances the aroma, softens the smoke, and significantly improves the quality of the tobacco (Non-Patent Documents 8-10).
  • the CBT content in tobacco is usually up to about 6000 ppm, and if a large amount of tobacco raw material is used to increase the amount of CBT in a smoking article, the content of alkaloids, including nicotine, will also increase accordingly.

  • a solution containing purified CBT was prepared. An amount of this solution equivalent to 6,000 ppm of CBT was added to the extraction residue to obtain tobacco material.
  • the tobacco material had a CBT content of 7,800 ppm and a total nitrogen content of 0.6% by weight. In other words, the CBT/total nitrogen ratio was 1.25.
  • Example 6 (mixing non-tobacco materials) A concentrated ethanol solution of CBT was obtained in the same manner as in Example 1. Tobacco powder consisting of flue-cured and burley varieties was mixed with cellulose fiber, carboxymethylcellulose, glycerin, and the concentrated ethanol solution of CBT, and water was added and kneaded. The kneaded mixture was laminated to obtain a sheet-shaped tobacco material. The CBT content of the tobacco material was 8519 ppm, and the total nitrogen content was 3.5 wt %. In other words, the CBT/total nitrogen ratio was 1.31.
  • Example 7 The tobacco segments shown in Figure 1 were prepared from the tobacco materials obtained in the Comparative Example and Examples 1 to 6. Next, non-combustion heating smoking articles including the tobacco segments were manufactured, and smoking tests were conducted by four expert panelists. Evaluation factors included the smoke volume and mouth feel during smoking, which were evaluated on a seven-point scale. The higher the score for smoke volume divided by the score for mouth feel, the more desirable the sensory characteristics.
