摘要
采用水蒸气蒸馏法提取窄叶鲜卑花叶挥发油,通过气相色谱-质谱联用(GS-MS)技术对其挥发油中化合物成分进行分析鉴定,并用峰面积归一化法确定各组分的相对含量。共鉴定出50种化合物,主要成分为:亚油酸(12.85%)、植酮(11.4%)、二十八烷(10.81%)、棕榈酸(9.22%)、正二十三烷(7.58%)、法尼基丙酮(5.62%)、邻苯二甲酸二异辛酯(3.29%)、邻苯二甲酸二异丁酯(3.21%)、肉豆蔻酸(3.03%)、反式-橙花叔醇(2.14%)、月桂酸(2.11%)、雌二醇(1.9%)等。窄叶鲜卑花叶挥发油种类较多,以脂肪酸、烷烃类和萜类物质为主。
The extraction of volatile oil from leaves of Sibiraea angastata was by steam distillation.The components of volatile oil were identified by gas chromatography-mass spectrometry( GC-MS).The relative content of each component was determined by peak area normalization method.Totally 50 compounds were separated and identified, mostly including : 9,12- octadecadienoic acid( Z, Z) ( 12.85% ), 2 - pentadecanone, 6, 10, 14 - trimethyl ( 11.4% ), octacosane ( 10.81% ), n- hexadecanoic acid (9.22%),tricosane (7.58%),5,9, 13- pentadecatrien-2- one, 6, 10, 14- trimethyl-, (E, E) (5.62%), 1,2- benzenedicarboxylic acid, diisooctyl ester ( 3.29% ), 1,2 - benzenedicarboxylic acid, bis ( 2 - methylpropyl ) ester ( 3.21% ), teradecanoic acid( 3.03% ), 1,6,10 - dodecatrien - 3 - ol, 3,7,11 - trimethyl -, ( E ) ( 2.14% ), dodecanoicacid ( 2.11% ), estradiol;estradiol (1.9%)ect.There were many kinds of Sibiraea angustata leaf volatile oil,fatty acids, alkanes and terpenoids were the main ones.
