| Summary: | This study aimed to determine the chemical composition of five <i>Lavender</i> essential oils (LEOs) using the gas chromatography–mass spectroscopy technique and to assess their antibacterial activity against four marine <i>Vibrio</i> species, including <i>Shewanella algae</i>, <i>Shewanella maridflavi</i>, <i>Vibrio harveyi</i>, and <i>Vibrio alginolyticus</i>. Sensitivity tests were performed using the disk diffusion and serial dilution methods. The results showed that all five LEOs exhibited antibacterial activity against the four tested marine <i>Vibrio</i> species. The antibacterial activities of all five LEOs were above moderate sensitivity. The five LEOs from French blue, space blue, eye-catching, and true <i>Lavender</i> showed high sensitivity, particularly against <i>Shewanella maridflavi</i>. The compounds of LEOs from different varieties of <i>Lavender</i> were similar and mainly comprised linalool, linalyl acetate, eucalyptol, and isoborneol. Different varieties of LEOs possessed unique components besides common components, and the percentage of each one was different, which led to different fragrance loads. The major fragrances were lily of the valley, an aromatic compound fragrance, and an herbal fragrance. The antibacterial activity of LEO from eye-catching <i>Lavender</i> was better than that of others, which could provide a reference for its application in the prevention and control of marine <i>Vibrio</i> spp. and the development of antibacterial products. |
