摘要
对舟山新木姜子材料不同时期的叶片挥发性成分含量进行分析,研究其不同季节挥发性成分含量的动态变化以及挥发油的抑菌和抗氧化效果。结果表明:夏季挥发油含量最高为5.4%,精油的主要挥发性成分是酯类、单萜和倍半萜。抑菌性实验结果表明精油具有抑菌效果,且效果随着浓度的升高而增大。抗氧化性实验通过DPPH自由基清除实验表明舟山新木姜子精油精油具有较强的抗氧化性。
The content of volatile components in leaves of Neolitsea sericea was analyzed at different stages,study on the dynamic changes of volatile components in different seasons and the antibacterial and antioxidant effects of volatile oil.The results showed the highest volatile oil content in summer was 5.4%,the essential volatile components of essential oils was esters,monoterpenes and sesquiterpenes.The results of antibacterial test showed that the essential oil had bacteriostatic effect,and the effect increased with the increase of the concentration.Antioxidant activity of DPPH free radical scavenging experiment showed that Neolitsea sericea essential oil had strong antioxidant activity.
