摘　　要：[目的]研究甜叶菊在不同温度下的裂解行为,初步探讨甜叶菊可能的裂解机理。[方法]采用离线热裂解气相色谱-质谱联用法(Py-GC/MS),并以GC/MS对其裂解产物进行定性分析。[结果]裂解温度对甜叶菊产生的裂解产物种类和含量影响较大,裂解机理不尽相同。在300、600、900℃下的热裂解产物中分别鉴定出13、75、95种裂解产物,致香物质主要有醛类、吡嗪、酚类等,这些产物可改善烟气质量,提高卷烟品质。[结论]该研究考察Py-GC/MS方法为制备新型再造烟叶原料筛选提供参考,也为甜叶菊在造纸法再造烟叶中的应用提供依据。[Objective]To study the pyrolysis behavior of Stevia rebaudiana at different temperatures,and to preliminary explore the possible pyrolysis mechanism of Stevia rebaudiana.[Method]By off-line pyrolysis-gas chromatography-mass spectrometry(Py-GC/MS),the pyrolysis products were directly introduced into GC/MS and qualitatively analyzed.[Result]The pyrolysis temperature had a great influence on the types and contents of the pyrolysis products produced by Stevia rebaudiana,and the pyrolysis mechanisms were different.There were 13,75 and 95 kinds of pyrolysates identified at temperature of 300,600 and 900℃.Aroma components included aldehydes,pyrazines,phenols and so on.These products could improve the quality of smoke and cigarette quality.[Conclusion]The research gave references for the study of Py-GC/MS method for the preparation of new reconstituted tobacco raw material selection.It also provided basis for the application of Stevia rebaudiana in paper-making reconstituted tobacco.
