为探究通过香叶植物混合模拟获得玫瑰精油香气的可能性，采用顶空固相微萃取结合气相色谱-质谱联用法，选取蔷薇科、禾本科、唇形科、山茶科和芸香科等9个科11种香叶植物，对其叶片的挥发性成分进行定性与定量分析。结果显示：11种植物材料中共有主要挥发性物质78种，其中萜烯类39种，脂肪酸衍生物类23种，苯环/苯丙素类化合物16种；利用Matlab软件分析，以玫瑰精油香气为模拟对象，确定香叶植物混合质量比例，迷迭香、鄂茶10号、柠檬桉和香叶天竺葵以质量比31∶7∶11∶1进行混合。结果表明：萜烯类化合物是香叶植物的主要挥发物类型，其次是脂肪酸衍生物类和苯环/苯丙素类化合物；混合模拟叶片组最终模拟获得与玫瑰精油香气相似的混合香气，主要成分为香茅醇、香叶醇、芳樟醇和石竹烯。
The headspace solid-phase microextraction combined with gas chromatography-mass spectrometry （HS-SPME-GC-MS） was used to qualitatively and quantitatively analyze the volatile compounds in the leaves of 11 plants with aromatic leaf selected from 9 families including Rosaceae， Poaceae， Lamiaceae， Theaceae， Rutaceae and other families to study the possibility of obtaining the aroma of Damascus rose essential oil with mixed simulation of plants with aromatic leaf. The results showed that a total of 78 major volatile compounds including 39 terpenes， 23 fatty acid derivatives， and 16 benzenoid/phenylpropanoids were detected in the 11 tested plants. MATLAB software was used to analyze and simulate the aroma of rose essential oil to determine the mixed mass ratio of plants with aromatic leaf. The results of mixing the leaves of Rosemary， Echa No.10， Eucalyptus citriodora and Pelargonium graveolens in a mass ratio of 31∶7∶11∶1 showed that terpenoids were the main volatile compounds in plants with aromatic leaf， followed by fatty acid derivatives and benzenoid/phenylpropanoids. The group with mixed simulation of plants with aromatic leaf ultimately obtained a mixed aroma similar to that of rose essential oil， mainly composed of citronellol， geraniol， linalool， and caryophyllene.
