In order to study the application value of T hamnolia vermicularis (Ach .) Asa-hina .ex-tract in cigarette ,the extract was prepared and added to cigarette .The paper studied flavor com-ponents of cigarette ,the toxic components in mainstream smoke ,hazard index and sensory evalua-tion ,indicating that the Thamnolia vermicularis (Ach .) Asa-hina .extract increased aroma com-ponents of cigarette smoke by 41 .68% ,the main aroma components of cigarette such as neophyta-diene by 64 .27% ,benzaldehyde by 14 .47% ,benzyl alcohol by 104 .85% ,tetradecanal by 118.53% ,andβ-lonone by 116 .45% .The sensory evaluation result showed that the Thamnolia vermicularis (Ach .) Asa-hina .extract effectively improved the richness and flavor of cigarette .In addition ,the harmful components in mainstream smoke were reduced generally ,phenol and NH3 were reduced by 33 .73% and 42 .13% ,and the hazard index of cigarette was reduced by 0 .86% . So the Thamnolia vermicularis (Ach .) Asa-hina .extract has a high application value in cigarette .%为研究雪茶提取物在卷烟增香降害方面的应用价值，在保证雪茶原料安全性前提下，制备雪茶提取物并将其添加到卷烟中，研究雪茶提取物对卷烟烟气致香成分含量、主流烟气有害成分含量和危害性指数的影响，并对其进行感官质量评吸，结果表明：添加雪茶提取物的卷烟烟气致香成分总量较未添加的卷烟增加了41.68％，主要致香物质新植二烯含量增加64.27％、苯甲醛含量增加14.47％、苯甲醇增加104.85％、十四醛增加118.53％、β紫罗兰酮增加116.45％；感官质量评吸结果显示，添加雪茶提取物能有效提升卷烟烟气的丰富性和韵调；卷烟主流烟气有害成分含量普遍降低，其中苯酚、N H3含量分别降低了33.73％、42.13％，危害性指数降低0.86％。可见，雪茶提取物在卷烟中具有较高的增香降害应用价值。
