| 摘 要： | 通过水蒸气蒸馏法提取杉木心材精油,并进行柱层析分离、气 质联用分析和抑菌活性试验，比较分析了精油含量、化学组成和抑菌活性成分.结果表明,杉木心材精油含量为1.794～2.076（w/w）；气-质联用分析共分离出47个色谱峰，鉴定出27个化合物（占精油总量的99％），其中主要成分为柏木脑（76.27%）；杉木心材精油对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌、伤寒沙门氏菌等均有较明显的抑制作用；柏木脑是杉木精油的主要抑菌活性成分.

| Abstract: | In this study, the essential oils in Cunninghamia lanceolata heartwood were water-steam distilled, and their chemical components were analyzed by column chromatography and GC-MS, with their antimicrobial activity tested. The results showed that the essential oils content was 1.794-2.076 (w/w), and 47 peaks were separated. 27 compounds, accounted for 99% of crude essential oils, were identified. The essential oils had an obvious antimicrobial activity against Escherichia coli, Staphylococcus aureus, Bacillus sabtills and Salmonella typhi, and cedrol, occupying 76.27% of essential oils, was the major component with antimicrobial activity. |
