摘要: 采用 GC-MS-计算机联用技术,对夜间采集的夜来香嫩枝挥发油进行成分分析。从夜间嫩枝的挥发油中鉴定出49种化合物,占总量的80.98%,主要含甲酸二十一酯(11.28%)、沉香烷(9.70%)、2-亚油酸甘油酯(7.89%)及驱蚊叮、二十一烯、1,3-二甲苯、1,2,3-三甲苯、4-乙基-1,2-二甲苯、二十四烷、2,4-二叔丁基苯酚、3-乙基甲苯等。对照夜间花朵挥发油成分,夜间嫩枝挥发油成分有近三分之一成分相同; 相同成分含量约占挥发油含量的45%;且嫩枝含油量也较高,约2.22%;可为夜来香的全面开发利用提供更多依据。

Abstract: The essential oil of branch at night from Cestrum nocturnum Linn was analyzed and determined by GC/MS. 49 compounds were obtained and identified in the oil . The main constituents were 1-Heneicosyl formate(11.28%); Docosane(9.70%); 2-mono-Linolein(7.89%); Dibutyl phthalate; 10-Heneicosene(c,f); 1,3-dimethy Benzene; 1,2,3-trimethyl Benzene ; 4-ethyl-1,2-dimethyl Benzene; Tetracosane; 2,4-bis(1,1-dimethylethyl)-Phenol ; 1-ethyl-3-methyl Benzene, etc. Their toral content was 80.98% of the identified volatile compounds.
