采用同时蒸馏萃取法,从卷烟主流烟气中萃取中性香气成分,对其进行气相色谱(GC)分析和气相色谱/质谱(GC/MS)鉴定.结果表明,在萃取时间为2 h,水浴温度为60 ℃的条件下,同时蒸馏萃取法能提取和分离出主流烟气中多种主要中性香气成分.在提取得到的中性香气成分中,质谱鉴定出了72种,其中:烃类17种,醛类7种,酮类23种,醇类9种,酯类8种,醌类1种,含氧杂环类2种,含氮化合物5种.所测标样的回收率为70.9%～85.4%.提取的25种含量较高的中性香气成分中,除植醇外,相对标准偏差均在10%以下.

The neutral flavor components in mainstream cigarette smoke were extracted by using simultaneous distillation and extraction equipment and determined by GC and GC/MS. After 2 hours of extraction at water temperature, 60 ℃, 72 kinds of neutral flavor components were identified. Theses components include 17 hydrocarbons, 7 aldehydes, 23 ketones, 9 alcohols, 8 esters, 1 quinone, 2 miscellaneous oxygennated compounds and 5 nitrogenous compounds. 25 of these components were determined quantitatively. The recoveries of the method ranged from 70.9% t...
