以山楂和橄榄两种植物作为试验原料,采用溶剂浸泡、回流、浓缩的工艺制备得到山楂提取物和橄榄提取物,再以一定的比例复配得到复合提取物.通过添加丙二醇溶解提取物后,添加到卷烟中加香.评吸结果显示,山楂提取物和橄榄提取物以2:1比例复配得到的复合提取物能够显著改善卷烟的品质,表现在香气量尚足,香气质好,余味稍减弱,杂气减弱,谐调性加强,刺激性稍有加强.利用GC-MS分析复合提取物中的挥发性成分,发现山楂提取物和橄榄提取物的复配能够起到互补的作用,检测到了70种挥发性成分,主要有酯类27种、醛类15种、烯类17种、有机酸类3种、醇类3种、酮类2种,这些物质奠定了其改善卷烟评吸效果的物质基础.%Two plants of hawthorn and olives were used as experimental materials,hawthorn extract and olive extract were prepared by solvent soaking,refluxing and concentrating process,and then composite extracts were obtained in a certain proportion. After the extract was dissolved by the addition of propylene glycol,sample was added to the cigarette for flavoring. Smoking results showed that,hawthorn extract and olive extract in a 2:1 ratio of complex can significantly improve the quality of cigarettes,and the aroma is still sufficient,good aroma quality,aftertaste slightly weakened,mixed gas weakened,harmony en-hanced,the stimulus slightly strengthened. GC-MS analysis of volatile composites in composite extracts indicated that the ex-tract of hawthorn and olive can play a complementary role. 70 kinds of volatile components were detected, including mainly 27 kinds of esters,15 kinds of aldehydes,17 kinds of alkenes,3 kinds of organic acids,3 kinds of alcohols and 2 kinds of ketones,which laid the substance foundation for improving cigarette smoking effect.
