Abstract：In order to study the pyrolysis behavior of loquat leaf extract that pyrolysates effect to the compo-nent of cigarette smoke,the pyrolysates were investigated in N2 ,N2 containing 10%O2 and at three temper-ature levels of 300 ℃,600 ℃and 900 ℃,respectively.The pyrolysates were directly introduced into GC-MS,qualitative analysis of the pyrolysates by mass spectrometry,and a semi-quantitative analysis by area normalization were made.The results showed that loquat leaf extract anaerobic pyrolysis products were mainly the aldehydes,alcohols and phenols,and aerobic pyrolysis products were mainly carboxylic acids, ketones and phenols,etc.The pyrolysis products could produce grassy,spicy,fragrant baked ,caramel a-roma,nutty aroma,sweet,floral and other rhyme tune,which could enrich the aroma of cigarettes.The a-mount of these pyrolysates under aerobic conditions was more than anaerobic pyrolysates,the oxygen intro-duced could exacerbate the pyrolysis of loquat leaf extract.With the increase of temperature,pyrolysis was <br> more and more complex,benzenes and polycyclic aromatic hydrocarbons substances released was found to inerease.
