Analysis of Pyrolysates from Fenugreek Absolute by On-Line Pyrolysis-Gas Chromatography/Mass Spectrometry
摘要
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 per-centage with increasing temperature (600~800 ℃).In addition,the flavor mechanism and the attribu-tion of benzene compounds were investigated.关键词
