This invention provides smoking compositions which contain a novel flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as 2-(3-hexyl-2-hydroxy-4-phenyl-3-buten-1-yl)--3,5,6-trimethylpyrazine releases pyrazine and cinnamaldehyde type of volatile flavorants into the cigarette smoke: ##STR1## A present invention flavorant-release additive is represented by the formula ##STR2## where R is hydrogen or methyl, R.sup.1 is hydrogen or a C.sub.1 -C.sub.10 alkyl substituent; and R.sup.2 is hydrogen or a C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy substituent.
                            本发明提供了含有一种新型
香料释放添加剂的吸烟组合物。在香烟吸烟条件下,可燃填料和/或纸包添加剂,如2-(3-己基-2-羟基-4-苯基-3-
丁烯-1-基)-3,5,6-三甲基
吡嗪,释放出
吡嗪和肉桂
醛类挥发性
香料到香烟烟雾中:##STR1## 本发明的
香料释放添加剂由以下公式表示:##STR2## 其中R为氢或甲基,R.sup.1为氢或C.sub.1-C.sub.10烷基取代基;R.sup.2为氢或C.sub.1-C.sub.4烷基或C.sub.1-C.sub.4烷氧基取代基。
