| 摘 要： | 采用热重-红外-气质(STA-IR-GC-MS)联用技术,对上、中、下不同部位烟叶在不同失重点下的裂解产物进行在线检测分析。结果发现:不同部位烟叶在270℃时均能释放出非挥发性多羟基成分,例如甲基-L-吡喃阿拉伯糖甙、甲基葡萄糖甙、甲基-α-D-吡喃甘露糖甙等,而在350℃时主要释放气相成分;在不同失重点均能产生粒相物烟碱,但中部烟叶在270℃和350℃时释放出的总成分明显多于上部和下部。此方法前处理省时便捷。 |

| Abstract: | In this study,the STA-IR-GC-MS technology is adopted to detect and analyze the pyrolysis products of the KB2F,KC2F,KX2F at different thermal decomposition temperature.It is found that non-volatile more hydroxyl components,for example methyl-α-L-arabinopyranoside,6-deoxy-methyl-α-L-galactopyranoside,α-methyl-D-mannopyranoside are released at 270℃ and gas components are released at 350℃,respectively.Further investigation reveals that KC2F releases significantly more components than KB2F and KX2F at 270℃ and 350℃ and it reaches to the maximum at 350℃.S]-3-1-methyl-2-pyrrolidinyl]-pyridine is released at different thermal decomposition temperature in different parts of tobacco.It is a simple,time saving,and convenient method for detecting non-volatile more hydroxyl components and volatile components of smoke components in different parts of tobacco. |
