摘    要:利用GC/MS联用技术,对橙叶油挥发性成分进行分析,并用峰面积归一化法计算各成分相对含量。通过质谱库检索,辅助保留指数比对,共分析并确定出橙叶油中的56种成分,占橙叶油挥发性成分的97.471%。主要成分为乙酸芳樟酯(30.685%)、芳樟醇(22.166%)、α 松油醇(9.040%)、乙酸香叶酯(5.696%)、月桂烯(3.716%)、乙酸橙花酯(3.573%)、柠檬烯(3.263%)、β 蒎烯(2.943%)、橙花醇(2.314%)、(E) β 罗勒烯(1.941%)、β 石竹烯(1.851%)、γ 松油醇(1.557%)、α 蒎烯(1.332%)、(Z) β 罗勒烯(1.300%)。通过保留指数来鉴别顺反同分异构体,提高了天然香原料中化合物定性的准确性。上述研究结果可为橙叶油产品开发、应用提供参考。

关 键 词:橙叶油  气相色谱/质谱  挥发性成分  保留指数

Abstract:The volatile components of petitgrain oil were analyzed by GC/MS, and the peak area normalization method was used to calculate the relative content of each component. With the mass spectrometry library search, 56 compounds which accounted for 97.471% in the volatile components of petitgrain oil, were confirmed using retention index comparison. Linalyl acetate (30.685%), linalool(22.166%), alpha terpineol(9.040%), geranyl acetate(5.696%), myrcene(3.716%), neryl acetate(3.573%), limonene(3.263%), beta pinene(2.943%), nerol(2.314%), (E) beta ocimene(1.941%), beta caryophyllene(1.851%), gamma terpineol(1.557%), alpha pinene,(1.332%), (Z) beta ocimene(1.300%) were the main components. The cis(trans) isomers were confirmed by retention index, and the accuracy of compound qualitative analysis in natural flavor was improved. These results provided the technical support for the development and application of petitgrain oil.
Keywords:petitgrain oil  GC/MS  volatile components  retention index
