青岛海域浒苔中挥发油成分分析

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

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-Octadecatrien-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-Octadecadienoic 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%。

The essential oil of Enteromorpha prolifera obtained in Qingdao sea area was extracted by steam distil- lation 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-l-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%）, Eico- sane（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.
