摘要: 为探索迷迭香精油对金线莲尖孢镰刀菌的抑菌活性,通过水蒸汽蒸馏法提取5个不同品系迷迭香叶精油,菌丝生长抑制法测定精油对尖孢镰刀菌的抑菌活性。结果表明:5个品系的迷迭香精油均有一定的抑菌活性,其中匍匐迷迭香和粉花迷迭香精油的活性最强,在体积浓度分别为0.15%和0.25%时对金线莲尖孢镰刀菌的抑菌率在50%以上。通过气相色谱-质谱联用(Gas chromatograph- mass spectrometer,GC-MS)技术对5个品系迷迭香精油挥发性成分进行分析和比对,发现其中的樟脑、桉叶油醇和β-蒎烯在匍匐迷迭香和粉花迷迭香中的含量相对较高。

Abstract: The present study aims to evaluate the antifungal activitity of 5 Rosmarinus essential oils (EOs) against Fusarium oxysporum, the causal agent of Anoectochilus roxburghii Stem Rot. The phytochemicals of 5 EOs were also determined and qualified by GC-MS methods. Based on the results, The R. officinalis L. 'Severn sea' EO and R. officinalis L. 'Majorca Pink' EO had the strongest activity, the inhibitory rates against F. oxysporum with an EC50 value of 0.15% and 0.25%, more potent than nystatin (0.005%), as a standard antifungal agent. Camphor, eucalyptol and β-pinene were identified as major components in both Rosmarinus officinalis L. 'Severn sea' EO and R. officinalis L. 'Majorca Pink' EO.

Key words: essential oil, Fusarium oxysporum, rosemary, antibacterial activity
