摘要: 采用同时蒸馏萃取法(SDE)提取盛花期紫丁香花精油,提取率为0.079%。用气相色谱-质谱法(GC-MS)结合气相色谱保留指数定性方法,从紫丁香花精油中鉴定出64种挥发性成分,占精油总成分的95.79%。主要成分为苯乙醇(16.12%)、(E,E)-法尼醇(13.43%)、苯甲醇(6.24%)、紫丁香醛C(3.91%)、肉桂醇(3.64%)、紫丁香醇A(3.61%)、4-乙烯基愈创木酚(3.38%)、紫丁香醛A(2.62%)、吲哚(2.34%)、苯甲酸苄酯(2.31%)、紫丁香醇D(2.25%)和苯乙醛(2.03%)等。其中所含的紫丁香醛异构体和紫丁香醇异构体是紫丁香鲜花的特征香气成分。

Abstract: Essential oil in flowers of Syringa oblata Lindl. at full-bloom stage was extracted by simultaneous distillation and solvent extraction (SDE). The yield of oil obtained is 0.079%. Sixty-four components are identified by GC-MS according to retention indices(RI), covering 95.79% of the total components, which are phenylethyl alcohol (16.12%), (E,E)-farnesene (13.43%), benzyl alcohol (6.24%), lilac aldehyde C (3.91%), cinnamyl alcohol (3.64%), lilac alcohol A (3.61%), 2-methoxy- 4-vinylphenol (3.38%), lilac aldehyde A (2.62%), indole (2.34%), benzyl benzoate (2.31%), lilac alcohol D (2.25%) and phenylacetaldehyde (2.03%). The isomers of lilac alcohol and of lilac aldehyde are the characteristic aroma components of flower of Syringa oblata Lindl.
