烟草二氧化碳超临界萃取物的初步研究

Preliminary Study on Carbon Dioxide Supercritical Fluid Extraction of Tobacco

初步探索了二氧化碳超临界流体萃取烟草成分的技术参数 ,采用气相色谱仪和气质联用仪分析了烟草萃取物。结果表明 ,二氧化碳超临界萃取物以非极性和弱极性化合物为主。另外对上海烟草 (集团 )公司的 4种牌号卷烟产品萃取物的相对定量分析结果表明 ,“中华”牌卷烟的萃取物含量最高 ,“双喜”次之 ,“牡丹”第三 ,“前门”的最低。

Technical condition for carbon dioxide supercritical fluid extraction of tobacco was studied. The analysis results of the extraction by GC and GC/MS showed that the tobacco extraction with carbon dioxide supercritical fluid was mainly non\|polar and low polar compounds. The flavor components in the carbon dioxide supercritical extraction of four brands of cigarettes were analyzed quantitatively with the internal standard method. The rank of the total amounts extracted by CO\-2 from 4 brands of cigarettes was as follows: Zhonghua>Shuangxi>Mudan>Qianmen.
