摘要: 利用水蒸气蒸馏法提取白兰花中的挥发性成分,通过气相色谱质谱联用技术(GC-MS)并结合计算机分析鉴定提取物中挥发油芳香成分,共鉴定出76个化合物,其中有37个萜类化合物、17个醇类化合物、6个烷烃类化合物和其它类型化合物。用面积归一化法测定挥发油中各种成分的相对含量,合计占总峰面积的93292%。同时对不同菌株进行抑菌实验,并探究不同浓度挥发油对粘虫的拒食作用。实验结果表明:用水蒸气蒸馏提取白兰花挥发油时,提取率为4.18%,其最主要成分为芳樟醇;该方法提取的白兰花挥发油对水稻黄单胞菌和枯草芽孢杆菌抑制作用最好,并且对粘虫幼虫有很好拒食活性。

Abstract: Volatile oils were obtained from the flowers of Michelia alba DC.by means of steam distillation technique.The volatile components in the extracts were analyzed by GC-MS and their relative contents were identified by peak area normalization method.The results showed that there are 76 identified compounds which include 37 terpenoids,17 alcohols,6 alkane compounds and other substances in the essential oils.The relative contents of all detected compounds in the essential oils are 93.026%.In addition,we conducted antimicrobial experiments with different strains,and explored the antifeedant properties of essential oils in different concentrations against the worm Mythimna separata.The experimental results showed that the extraction rate was 4.18% by using steam distillation extraction method.The most abundant component of the extracted oil is linalool.The essential oils showed most potent inhibitory activity against Xanthomonas oryzae and Bacillus subtilis among the tested strains and it had a good inhibitory effect on the armyworm Mythimna separata.
