为了研究云南滇红玫瑰和墨红玫瑰的香气成分并对比其差异;通过水蒸气蒸馏法提取两种玫瑰花的香气成分,并以GC-MS方法对滇红玫瑰和墨红玫瑰的香气成分进行鉴定和定量分析;在滇红玫瑰中主要检测出61种香气物质,在墨红玫瑰中主要检测出63种香气物质;滇红玫瑰香气成分主要为醇类物质(58.41%),醛类物质(8.42%)、酯类物质(7.42%)、烷类(5.43%)、含氮类(3.49%)、酮类物质(1.85%)、酸类物质(1.7%)和醚类物质(1.43%);墨红玫瑰香气成分的种类主要为醇类(51.93%)、醛类(11.98%)、醚类(7.78%)、酯类(6.05%)、烷类(3.95%)、酸类(3.39%)、甲氧基化合物(3.06%)、萜类(0.16%);滇红玫瑰和墨红玫瑰共有44种相同的香气物质,但两种玫瑰香气成分及含量均有差异。
The aroma components of Dian Hong Roses and Mo Hong Roses were analyzed, their differences were compared;the aroma components from these two roses were extracted by vapour distillation. And their aro－ ma components were analyzed by GC-MS. After the detection, 61 kinds of aroma components from Dian Hong Roses and 63 kinds aroma components from Mo Hong Roses were detected; the aroma components of Dian Hong Roses contained alcohol which account for 58.41 % in total, aldehyde（8.42 %）, esters（7.42 %）, alkane（5.43 %）, nitrogen-containing compounds（3.49 %）, ketone（1.85 %）, acids（1.7 %）,and ethers（1.43 %）. The aro－ ma components of Mo Hong Roses contains alcohol which accounted for 51.93 % in total, aldehyde（11.98 %）, ethers（7.78 %）, esters（6.05 %）, alkane（3.95 %）, acids（3.39 %）,oxygen based compounds（3.06 %）, and terpene（0.16 %）. Although Dian Hong Roses and Mo Hong Roses had 44 kinds aroma components in common, their aroma components content and kind still had differences.
