摘要/Abstract

摘要：

采用水蒸气蒸馏法从披针叶胡颓子中提取挥发油，出油率为0.53％。通过GC-MS对其挥发油的成分进行了色谱分析，在最佳分析条件下，共分离出31个峰，并对其化学成分进行了分析，鉴定出了26个化学成分，鉴定率为83.9%。其主要成分为4-甲氧基肉桂酸辛酯、壬酸、亚油酸、棕榈酸、大根香叶烯D 、烷烃等。并对披针叶胡颓子挥发油的抑菌作用进行了研究。结果表明，披针叶胡颓子挥发油对大肠杆菌、金黄色葡萄球菌和枯草芽孢杆菌的生长均有较强的抑制作用。

Abstract:

The volatile oil in Elaeagnus lanceolata Warb. apud Diels is extracted by water-steaming method. The extraction rate is 0.53%. The chemical compositions of the volatile oil have been identified with the optimum separating and analyzing conditions by means of the GC-MS. The result shows 31 compounds are separated. The represention rate of tot-al volatile oil is 83.9％. The major chemical compositions of volatile oil in Elaeagnus lanceolata Warb. apud Diels are 4-methyl phenol，pelargonic acid , linoleic acid , palmitic acid , Germacrene D，hydrocarbon etc. The antibacterial activity of volatile oil in Elaeagnus lanceolata Warb. apud Diels has been studied. It showed that it has high antibacterial activity against E. coli、St. aureus、and B. subtilis.
