Abstract：In order to study the relationship between important neutral aroma components and smoking quality in upper leaf under artificial aging, the tobacco leaves from Zhucheng area were used as materials.The results were as follows: the contents of important neutral aroma components changed very significantly; the contents of carotenoid degradation products, Maillard reaction compounds, aromatic amino acid degradation products and other kind of neutral aroma constituents significantly increased by 82.67%, 63.16%, 276.74%and 73.77%, respectively, while the content of chlorophyll degradation products decreased by 32.33%;the contents of cembranenoid degradation products showed no significant change during artificial aging.The rela-tionships between Maillard reaction compounds and smoking quality were the closest and all were positive.The cembranenoid degradation products were positive to aroma quality and aftertaste;the aromatic amino acid deg-radation products had significant indirect effects on offensive odor, irritancy and total score with the correlation coefficients as 0.401, 0.576 and 0.344 respectively; the carotenoid and chlorophyll degradation products were detrimental to smoking quality;the other kind of neutral aroma constituents had little effect on smoking quality.The results of stepwise regression analysis showed that the relationship between neutral aroma compo-nents and smoking quality was very significant, and the coefficients of determination were all above 0.80, in a word, the equations were reliable to forecast.
