In order to reduce the harm of free radicals in cigarette smoke to human health, the effects of Herba ardisiae Japonicae, Dendranthema indicum, and grape seed extracts application were experimented.The results showed that comparing with the control, the gas phase free radicals in the smoke of cigarettes containing Herba ardisiae Japonica extract, grape seed extract and Dendranthema indicum extract at the rate of 5-10 nig/ kg decreased by 16.31％ to 19.73％ , 20.19％ to 23.73％ and 11.56％ to 14.85％ , respectively.While the gas phase free radicals in the smoke of cigarettes containing 10 mg/kg of the mixture of the three extracts ( w∶ w∶ w = 1∶1∶ 1) reduced by 32.87％ , meanwhile the tar and carbonyl compounds in cigarette smoke did not increased, and the cigarettes offered balanced aroma and good smoking quality.%为减少烟气自由基对吸烟者健康的危害,用矮地茶、葡萄籽、香菊复合提取物进行了降低卷烟烟气自由基试验.结果表明:添加5-10 mg/kg矮地茶提取物、葡萄籽提取物和神农香菊提取物的卷烟烟气气相自由基分别降低16.31%～19.73%,20.19%～23.73%和1 1.56%～14.85%;添加10 mg/kg 1:1:1矮地茶、葡萄籽和神农香菊复合提取物的卷烟烟气气相自由基降低32.87%,且不会导致烟气焦油、羰基化合物等有害成分释放量增加,烟香协调,燃吸品质较好.
