摘　　要：利用水蒸汽蒸馏法提取宁德产小鱼仙草(M osla d ianthera M ax im)挥发油,得油率为0.50%.应用色谱/质谱/数据系统联用方法分析了其挥发油的化学组成,检测到93个峰,共鉴定了62种化学成分并测定其相对含量,占总含量的98.114%.其中,香荆芥酚(27.229%)、香芹酮(12.326%)、百里香酚(11.027%)、β-石竹烯(7.246%)、柠檬烯(6.209%)、2-甲基-5-(1-异丙基)-乙酰苯酚(5.932%)、间伞花烃(4.982%)、艹律草烯(4.496%)为主要成分.对7种供试细菌的体外抑菌实验表明,该挥发油对金黄色葡萄球菌(S taphy lococcus aureus)、大肠杆菌(E scherich ia coli)、藤黄八叠球菌(S arcina lutea)、枯草芽孢杆菌(B acillussubtilis)、普通变形杆菌(P roteas vu lg aris)、短小芽孢杆菌(B acillus pum ilus)、甘薯薯瘟病原细菌(F asariumaxy ssp oram)有一定的抑制作用.The volatile oil of Mosla dianthera Maxim is extracted by water steaming method. The extraction rate is 0. 50%. The chemical components were analyzed by means of GC/MS/DS. Sixtytwo components , 98. 114% of total content , have been identified from 93 separated peaks. The main components were carvacrol （27.229%）, carvone （12.326%）, thymol （11.027%）, flcaryophyllene （7.246%）, limonene （6.209%）, 2-methyl-5- （1-methylethyl） -acetylphenol （5.932%）, m-cymene （4. 982%）, humulene （4. 496%）. The antibacterial experiments of the oil were studied on 7 tested strains in vitro, which showed that the oil had a certain antibacterial activity against Staphylococcus aureus, Escherichia coli, Sarcina lutea, Bacillus subtilis, Proteas vulgaris, Bacillus pumilus and Fasarium axyssporam.
