摘　　要：采用水蒸气蒸馏法从披针叶胡颓子花中提取挥发油,出油率为0.53%。通过对其挥发油成分进行色谱分析,在最佳分析条件下,共分离出31个峰,鉴定出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。并对披针叶胡颓子花挥发油的抑菌作用进行研究。结果表明,披针叶胡颓子花挥发油对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌和铜绿假单胞菌的生长均有较强的抑制作用。The volatile oil in the flowers of Elaeagnus lanceolata Warb. apud Diels was extracted by steam distillation wixh an oil yield of 0.53% and analyzed for chemical composition by GC-MS. Under optimum conditions, 31 peaks were separated and 26 of them （83.9%） were identified, mainly including octyl 4-methoxycinnamate, pelargonic acid, linoleic acid, palmitic acid, Germacrene D and hydrocarbons. The volatile oil had potent inhibitory effects on the growth of E. coli, St. aureus B, subtilis and P. aeruginosa.
