Several economically important crops, fruits and vegetables are susceptible to infection by pathogenic fungi and/or bacteria postharvest or in field. Recently, plant essential oils (EOs) extracted from different medicinal and officinal plants have had promising antimicrobial effects against phytopathogens. In the present study, the potential microbicide activity of × cv. 'Kristinka' (peppermint) EO and its main constituents have been evaluated against some common phytopathogens. In addition, the cell membrane permeability of the tested fungi and the minimum fungicidal concentrations were measured. The antifungal activity was tested against the following postharvest fungi: , , and , whereas antibacterial activity was evaluated against , , and pv. . The chemical analysis has been carried out using GC-MS and the main components were identified as menthol (70.08%) and menthone (14.49%) followed by limonene (4.32%), menthyl acetate (3.76%) and β-caryophyllene (2.96%). The results show that the tested EO has promising antifungal activity against all tested fungi, whereas they demonstrated only a moderate antibacterial effect against some of the tested bacteria.
几种具有重要经济价值的作物、水果和蔬菜在收获后或田间易受致病真菌和/或细菌的感染。最近，从不同药用植物中提取的植物精油（EOs）对植物病原体具有良好的抗菌作用。在本研究中，评估了× cv. 'Kristinka'（薄荷）精油及其主要成分对一些常见植物病原体的潜在杀微生物活性。此外，还测定了受试真菌的细胞膜通透性和最低杀菌浓度。对以下收获后真菌测试了抗真菌活性：，，和，而对，，和pv.测试了抗菌活性。使用气相色谱-质谱联用仪（GC-MS）进行了化学分析，主要成分鉴定为薄荷醇（70.08%）和薄荷酮（14.49%），其次是柠檬烯（4.32%）、乙酸薄荷酯（3.76%）和β-石竹烯（2.96%）。结果表明，受试精油对所有受试真菌具有良好的抗真菌活性，而对一些受试细菌仅表现出中等抗菌效果。
