目的:分析鉴定浙江蜡梅叶挥发油的化学成分组成。方法:采用水蒸气蒸馏法提取浙江蜡梅叶中挥发性化学成分,采用气相色谱-质谱-数据库(GC-MS-DS)联用技术对其化学成分进行分离鉴定。结果:共分离了37个峰并鉴定出其中33个化合物,用面积归一化法测定其相对百分含量,占挥发性化学成分总含量的97.78%。结论:浙江蜡梅叶挥发油中主要成分是:1,4-桉叶素(46.20%)、(Z)-2,6,10-三甲基-1,5,9-十一烯(9.71%)、1,1-二甲基-3,4-二异丙烯基-环己烷(7.42%)、三辛胺(6.44%)、α-丙酸萜品酯(4.01%)、α-蒎烯(3.92%)等。
Objective: To analyze and identify the chemical constituents of the volatile oil of Chimonanthus praecox. Methods: Volatile constituents from the leaves of Chimonanthus praecox were extracted by steam distillation. The chemical constituents were isolated and identified by gas chromatography-mass spectrometry-mass spectrometry (GC-MS-DS). Results: A total of 37 peaks were isolated and 33 of them were identified. The relative percentages were determined by area normalization, accounting for 97.78% of the total volatile components. Conclusion: The main components of the volatile oil of Chimonanthus praecox are: eucalyptol (46.20%), (Z) -2,6,10-trimethyl-1,5,9-undecene ), 1,1-dimethyl-3,4-diisopropenyl-cyclohexane (7.42%), trioctylamine (6.44%), terpinyl a-propionate Ene (3.92%) and the like.
