香槟玫瑰花挥发油化学成分分析

Analysis of Chemical Components of Volatile Oils from the Flower of Champagne rose

[目的]研究香槟玫瑰花挥发油的化学成分。[方法]采用石油醚蒸馏提取法从香槟玫瑰花干样中提取挥发油,并用气相色谱-质谱联用仪(GC-MS)对其挥发油的化学成分进行鉴定。[结果]鉴定出46种主要化合物,其峰面积相对含量约占挥发油总量的87.77%。香槟玫瑰花挥发油的主要组分分别为乙醇(8.23%)、异丁醛(18.94%)、α-蒎烯(4.73%)、芳樟醇(4.09%)、乙酸金合欢酯(4.31%)、橙花醇(4.59%)、香茅醇(15.59%)、乙酸香茅酯(3.91%)、异丁香酚甲醚(2.58%)、缬草醛(7.73%)。[结论]该研究为进一步研究和开发香槟玫瑰花提供了科学依据。

[Objective]To study the chemical components of volatile oils from the flower of C.rose.[Method]The volatile oils were extracted from the dry flower of C.rose by distillation extraction of petroleum ether,and the chemical components of the volatile oils were analyzed and identified by the method of GC-MS.[Result]46 major compounds were separated and identified,which accounted for 87.77%of the total volatile oils.The main components of the volatile oils were Ethanol(8.23%),Isobutyraldehyde(18.94%),α-Pinene(4.73%),Linalool(4.09%),Farnesyl acetate(4.31%),Nerol(4.59%),Citronellol(15.59%),Citronellyl acetate(3.91%),Isoeugenol methyl ether(2.58%),Baldrin(7.73%).[Conclusion]The study provided scientific basis for further research and development of C.rose.
