青岛海域浒苔中挥发油成分分析

将青岛海域采集的浒苔在挥发油测定器中通过水蒸气蒸馏法提取,用 GC/MS 进行分离和检测,得到35种化合物。采用色谱峰面积归一法在MSD化学工作站下进行数据处理得到相对含量,其中主要成分及其含量为：棕榈酸(hexadecanoic acid,29.676%),顺-9,12,15-十八碳三烯-1-醇(9,12,15- Oc-tadecatrien-1-ol,(ZZZ)-,6.957%),鲨烯(Squalene ,5.567%),顺-11-十六碳烯酸(Z-11-Hexadecenoic acid ,4.494%),顺-7-十六碳烯酸(Z-7-Hexadecenoic acid,3.997%),9,12-十八碳二烯酸甲酯(9,12-Octade-cadienoic acid, methyl ester ,3.144%),十七碳酸(Heptadecanoic acid ,2.827%),邻苯二甲酸双庚酯(1,2-Benzenedicarboxylic acid, diheptyl ester,2.531%),二十碳烷(Eicosane,2.483%),十六碳酸甲酯(Hexadecanoic acid, methyl ester,2.468%),异植醇(Isophytol,2.183%),邻苯二甲酸单(2-乙基己基)酯(1,2-Benzenedicarboxylic acid, mono(2-ethylhexyl) ester,1.885%),油酸(Oleic acid,1.479%),14-甲基十七酸甲酯(Heptadecanoic acid,14-methyl-, methyl ester,1.473%)。这35种化合物占总检出量的82.199%。

Component Analysis of Essential Oil in Enteromorpha prolifera in Qingdao Sea Area

The essential oil of Enteromorpha prolifera obtained in Qingdao sea area was extracted by steam distillation method. The 40 chemical components were separated and identified by GC/MS. The relative content of each component was determined by area normalization in MSD chemical workstation. The experimental results showed that the major components were hexadecanoic acid(29.676%), 9,12,15-Octadecatrien-1-ol, (ZZZ)-(6.957%), Squalene(5.567%), Z-11-Hexadecenoic acid(4.494%), Z-7-Hexadecenoic acid(3.997%), 9,12-Octadecadienoic acid, methyl ester(3.144%), Heptadecanoic acid(2.827%), 1,2-Benzenedicarboxylic acid, diheptyl ester(2.531%), Eicosane(2.483%), Hexadecanoic acid, methyl ester(2.468%), Isophytol(2.183%), 1,2-Benzenedicarboxylic acid, mono(2-ethylhexyl) ester(1.885%), Oleic acid(1.479%), Heptadecanoic acid, 14-methyl-, methyl ester(1.473%). The 35 compounds occupy 81.096% of the total detectable amounts.
