模拟卷烟燃吸条件下款冬花浸膏的热裂解

Pyrolysis of Concrete of Tussilago farfara L. Under Simulated Cigarette Combustion Condition

在模拟卷烟燃吸状态下采用在线热裂解-气相色谱/质谱联用(Py-GC/MS)技术对款冬花浸膏进行了热裂解和裂解产物分析。结果表明:款冬花浸膏的热裂解产物中共鉴定出45种挥发性成分,主要包括5-羟甲基-2-呋喃甲醛(21.19%)、糠醛(5.34%)、亚油酸乙酯(3.96%)、棕榈酸乙酯(3.89%)、2,5-二甲酰基呋喃(3.75%)、5-甲基-2-呋喃甲醛(2.68%)和2-甲基丁酸(2.32%)等致香物质。该结果为款冬花浸膏在卷烟中的应用提供了参考。

Under simulated cigarette combustion condition,the pyrolytic behavior and the pyrolytic products of concrete of Tussilago farfara L. were studied by online pyrolysis-gas chromatography-mass spectrometry （Py-GC/ MS）. The results showed that： 45 kinds of volatile products were identified and the major components were 5-hydroxymethyl-2-furancarboxaldehyde （21.19%）, furfural （5.34%）, ethyl linoleate （3.96%）, ethyl hexadecanoate （3.89%）, 2, 5-furandicarboxaldehyde （3.75%）, 5-methyl-2-furancarboxaldehyde （2.68%）, 2-methylbutanoic acid （2.32%）.
