Investigation of the essential oil of the aerial parts of Eryngium maritimum L. from Corsica led to the isolation of one known sesquiterpene (1) and three new oxygenated sesquiterpenes with a muurolane or cadinane skeleton (2-4). Structure assignments of 4 βH -muurol-9-en-15-al (1), 4 βH -cadin-9-en-15-al (2), 4 βH -muurol-9-en-15-ol (3) and 4 βH -cadin-9-en-15-ol (4) were carried out by GC/MS (EI and CI) and comprehensive 1D and 2D NMR spectroscopy. Antibacterial activity of Eryngium maritimum L. oil and column chromatography fractions have been investigated for the first time. The oxygenated fraction, which contains the four sesquiterpenes, was efficient against Listeria monocytogenes and Echerichia coli.
对来自科西嘉岛的海狗葱地上部分的精油进行研究，分离得到一种已知的倍半萜（1）和三种具有愈创木烷或卡达烯骨架的新的含氧倍半萜（2-4）。通过 GC/MS（EI 和 CI）和综合 1D 和 2D NMR 光谱对 4βH-愈创木-9-烯-15-醛（1）、4βH-卡达烯-9-烯-15-醛（2）、4βH-愈创木-9-烯-15-醇（3）和 4βH-卡达烯-9-烯-15-醇（4）的结构进行了鉴定。首次对海狗葱精油和柱层析馏分进行了抗菌活性研究。含氧馏分含有这四种倍半萜，对单核细胞增生李斯特菌和大肠杆菌具有活性。
