天竺桂挥发油化学成分及抑菌活性研究

Bioactive Essential Oils from Cinnamomum japonicum Sibe

摘要:

用水蒸馏法提取天竺桂（Cinnamomum japonicum Sibe）挥发油，并用GC-MS分析化学成分，用滤纸片法测其抑菌活性.结果表明，从天竺桂挥发油中分离出27种化学成分,以冰片为主要成分,占26.03%;抑菌实验中，挥发油对大肠杆菌、枯草杆菌和金黄色葡萄球菌都有明显的抑菌作用。

Abstract:

The essential oils were extracted from the aerial parts of Cinnamomum japonicum Sibe by steam distillation and determined by GC-MS. Twenty-seven chemicals were isolated. Borneol was the major component accounting for 26.03% of the total oil. The essential oils exhibited significant activity against Escherichia coli, Bacillus subtilis and Staphylococcus aureus in the filter paper assay.
