中文摘要：

采用水蒸汽蒸馏法提取浙贝母精油，GC／MS分析法结合保留指数分析法鉴定精油化学成分，琼脂扩散法检测精油的抑菌活性。首次鉴定出浙贝母精油的15种化学成分，占精油总离子流色谱峰面积的97．48％，主要成分为正十六酸（53．46％），（E，E）－9，12－十八烷二烯酸甲酯（26．96％）和油酸（9．34％）。浙贝母精油对金黄色葡萄球菌和大肠杆菌均无抑制效果，对白色念珠茵有中等抑制作用。

英文摘要：

The essential oil from dried bulbs of Fritillaria thunbergii Miq. obtained by hydrodistil lation is analyzed by GC-MS together with Kovats retention index. The results show that major constituents of this oil are n-Hexadecanoic acid （53. 46%）, （E, E）-9, 12-Octadecadienoic acid （26.96%） and Oleic Acid （9.34%） and 15 chemical components are identified which represents 97. 5% of the total peak. The result tested by agar diffusion method shows that the oil has a moderate antifungal activity against Canidia albicans and no antimicrobial activity to Escherichia coli and Staphylococcus aureus.
