摘要

本研究旨在研究3种芳香植物精油对13株丝状真菌的抑菌活性。方法薄荷精油、麝香精油和月桂精油的主要成分分别为香芹酮(52.2%)、芳樟醇(78.1%)和1,8-桉叶脑(45.6%)。还有一些专利建议使用精油作为天然和安全的杀菌剂替代品来保护植物。结果薄荷精油对所有真菌的抑菌活性最强,其中对禾草镰刀菌、念珠镰刀菌和膨胀青霉最敏感,最小抑菌浓度(MIC)和最小杀菌浓度(MFC)均为2.5 μL mL-1 (v/v)。普通胸腺精油的活性低于木犀草精油。对百里香油最敏感的菌种是赭曲霉,MIC和MFC分别为2.5 μL mL-1和5 μL mL-1。除黑曲霉(MFC >20 μL-1)外,百里香精油对真菌均有中等程度的杀灭作用。对百里香精油的抗真菌活性与百里香精油相似,其中寄生蜂对百里香精油的抗性最强(MFC >20 μL mL-1)。结论使用这些精油可以替代人工合成杀菌剂,预防采前和采后感染,保证产品安全。

In Vitro Study of the Antifungal Activity of Essential Oils Obtained from Mentha spicata, Thymus vulgaris, and Laurus nobilis.
BACKGROUND The aim of this study was to determine the antifungal activity of the essential oils isolated from three aromatic plants against 13 filamentous fungal strains. METHODS The major constituents of Mentha spicata, Thymus vulgaris, and Laurus nobilis essential oils were carvone (52.2%), linalool (78.1%), and 1,8-cineole (45.6%), respectively. There are also some patents suggesting the use of essential oils as natural and safe alternatives to fungicides for plant protection. RESULTS In the present work, M. spicata essential oil exhibited the strongest activity against all tested fungi in which Fusarium graminearum, F.moniliforme, and Penicillium expansum were the most sensitive to mint oil with lower minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) values of 2.5 μL mL-1 (v/v). Thymus vulgaris essential oil was less active compared to the oil of M. spicata. Aspergillus ochraceus was the most sensitive strain to thyme oil with MIC and MFC values of 2.5 and 5 μL mL-1, respectively. Thymus vulgaris essential oil also exhibited a moderate fungicidal effect against the tested fungi, except for A. niger (MFC >20 μL-1). L. nobilis essential oil showed a similar antifungal activity with thyme oil in which A. parasiticus was the most resistant strain to this oil (MFC >20 μL mL-1). CONCLUSION Our findings suggested the use of these essential oils as alternatives to synthetic fungicides in order to prevent pre-and post-harvest infections and ensure product safety.
