摘要
近年来药用植物已成为抗耐药病原菌的首选来源。精油的抗菌作用早已为人所知。本研究对意大利蜡菊(Helichrysum italicum, Roth) G. Don, HIE)商品精油的化学成分和抑菌活性进行了评价。在油中鉴定出70种成分,占95.7%。HIE的主要成分为醋酸橙酯(15.6%)、α-蒎烯(11.5%)和γ-姜黄烯(11.3%)。采用琼脂孔扩散法和肉汤微量稀释法对其抑菌活性进行了筛选。除大肠杆菌耐药外,精油对其他细菌均有明显的抑菌活性。精油对金黄色葡萄球菌和铜绿假单胞菌的最低抑菌浓度为5 μg/mL,对蜡样芽孢杆菌和枯草芽孢杆菌的最低抑菌浓度为10 μg/mL。这些结果表明,意大利莲商品油具有作为天然抗菌剂的潜力。
Chemical Composition and Antibacterial Activity of Helichrysum italicum (Roth) G. Don Commercial Essential Oil from Serbia
Medicinal plants have been preferred sources against drug-resistant pathogens recently. The antimicrobial activities of essential oils have been known for a long time. In the present research, the chemical composition and antibacterial activity of commercial essential oil of Helichrysum italicum (Roth) G. Don (HIE) were evaluated. Seventy components which constitute 95.7%, were identified in the oil. The major constituents of HIE were neryl acetate (15.6%), α-pinene (11.5%), and γ-curcumene (11.3%). The oilwas screened for antibacterial activity by agar well diffusion and broth microdilution methods. The essential oil displayed remarkable antibacterial activity against test bacteria, except for Escherichia coli, which displayed resistance. The minimum inhibitory concentration (MIC) of essential oil were 5 μg/mL for Staphylococcus aureus and Pseudomonas aeruginosa, 10 μg/mL for Bacillus cereus and B. subtilis. These results suggested that the commercial oil of H. italicum has the potential to be used as a natural antibacterial agent.
