摘要

采用在线热裂解-气相色谱/质谱(PyGC/MS)联用技术研究了氦气氛围中葫芦巴净油在300、400、500、600、700、800 ℃下的热裂解行为。结果表明：① 在上述条件下共鉴定出86种裂解产物，主要是酯、酸、醇、烯烃类化合物；② 裂解温度低于500 ℃时，检测到的成分基本相同；③ 裂解温度从600 ℃升至800 ℃，检测到危害性的苯系物种类增多、相对含量增大。此外，对葫芦巴净油裂解产物的致香机理和苯系物的形成机理进行了简单讨论。

Abstract

Fenugreek absolute was pyrolyzed under helium atmospheres at 300

400

500

600

700 and 800 ℃

respectively. The pyrolysates were analyzed by online gas chromatography/mass spectrometry (GC/MS). The results showed that

first

eightysix constituents were identified

and the major of the pyrolysates were esters

acids

alcohols and alkenes. Second

the pyrolysates were almost same at lower temperature (300~500 ℃). Third

more and more benzene derivates were identified with higher percentage with increasing temperature (600~800 ℃). In addition

the flavor mechanism and the attribution of benzene compounds were investigated.
