Abstract This study was based on grafting with eggplant (eggplant as rootstock, flue-cured variety Yunyan 87 as scion), the content of TSNAs and the content of neutral aroma components in ultra-low nicotine tobacco leaves were determined and analyzed, and the smoke parameters and sensory quality of cigarettes were compared and analyzed. There were three treatments:"tobacco/tobacco", "tobacco/eggplant without hilling up", "tobacco/eggplant with hilling up". The results show that:(1) Ultra-low nicotine content in tobacco leaves grafted with eggplant, the contents of NNN,NNK,NAT and TSNAs were decreased significantly, the NNN,NNK and TSNAs contents of upper leaves tobacco/eggplant without hilling up were 82.71%, 79.46% and 68.78% lower than the control tobacco/tobacco, respectively. The NNN, NNK and TSNAs contents of the middle leaf tobacco/eggplant without hilling up were 79.68%, 79.80% and 68.63% lower than the control. (2) The change of neutral aroma components content in ultra-low nicotine tobacco leaves were small, The nicotine contents of mainstream cigarette smoke were decreased significantly, and the tobacco/eggplant without hilling up were 94.12% lower than the control, there was no significant difference in total particle matter, dampness, CO, tar in smoke and puff number. (3) there was no significant difference in aroma quality, concentration, irritancy and burning quality, aroma quantity, undesirable taste and after taste were decreased to some extent, and significant reduction in impact. Consumer satisfaction, pleasure, and acceptance were also decreased significantly. It can be concluded that the selective reduction of nicotine content had different effects on chemical composition and sensory quality of tobacco leaves produced by grafting technique.
