摘　　要：采用离线裂解装置分别在200℃,300℃,400℃三个不同温度点对-L-脯氨酸-1-脱氧-D-果糖(PF)进行裂解,用二氯甲烷收集产物,并采用GC/MS联用技术进行初步定性分析.结果表明PF在不同温度下裂解产物不一样,高温裂解产物较多;裂解产物大部分为杂环类化合物(如吡咯、吡咯烷类、呋喃、吡喃、呋喃酮、吡喃酮等等),这些物质是卷烟烟气中重要的致香成分.1-L-proline-l-deoxy-D-fructose （PF） was pyrolyzed at 200℃ ,300 ℃and 400℃ respectively. The pyrolytic products were collected by dichloromethane and analyzed with GC/MS qualitatively. The results show that different pyrolytic compounds are obtained at different temperatures, and more pyrolytic compounds are done in higher temperature and the maior pyrolytic compounds are heterocycle： Pyrrole, pyrroline, Furan, Pyran, Furanone, pyranone etc, which are the important component of producing flavor and aroma in gas from smoking.
