摘要：

以水蒸汽蒸馏法提取不同月份的天竺桂叶精油，测得精油含量变化范围约0.25～0.6mL/100g干叶，其中12月份精油含量相对较高，经GC-MS-DS分析表明该月份的叶精油主要化学成分为匙叶桉油烯醇(13.522%)、丁香烯(10.403%)、丁香烯氧化物(8.691%)、α,α-4-三甲基-3-环己烯-1-甲醇(8.293%)等，体外抗菌试验表明该精油对普通变形杆菌、藤黄八叠球菌、甘蓝黑腐菌、白菜软腐菌等均具有较强的抑菌活性。

Abstract:

The essential oil of Cinnamomum japonicum leaves from different months was extracted by steam distillation，its content was in 0.25～0.6mL/100g and reached the high level until December.And then, the main components of the essential oil in December were identified as Spathulenol(13.522%),Caryophyllene(10.403%),Caryophyllene oxide(8.691%),3-Cyclohexene-1-methanol,.alpha.alpha.4-trimethyl-(8.293%) by GC-MS-DS,the strong antibacterial activities against Proteus vulgaris、Sarcina lutea、 Xanthomonas campestris、Erwinia carotorora were also proved.
