Owing to their rich chemical composition, essential oils (EOs) have many interesting properties, including antimicrobial activities. The presence of and their secondary metabolites, mycotoxins, in cereal crops is a serious problem in agriculture, which consequently affects food quality. The aim of the present study was to investigate the effects of selected EOs on the growth of and and the biosynthesis of mycotoxins in maize seeds. Chromatographic analysis of ergosterol as a fungal growth indicator showed a significant inhibition of growth (83.24-99.99%) compared to the control samples, which as a consequence resulted in a reduction in mycotoxin concentrations. The addition of cinnamon, palmarosa, orange, and spearmint EOs was shown to be the most effective in reducing zearalenone concentration (99.10-99.92%). Deoxynivalenol analysis confirmed a very high reduction of this compound at the application all tested EOs (90.69-100%). The obtained results indicated that EOs have a great potential to inhibit growth of fungi as well as reduce the concentration of mycotoxins in maize seed.
由于其丰富的化学成分，精油具有许多有趣的特性，包括抗菌活性。谷物作物中存在霉菌及其次生代谢产物霉菌毒素是农业中的一个严重问题，进而影响食品质量。本研究的目的是调查所选精油对玉米种子中霉菌的生长以及霉菌毒素生物合成的影响。作为真菌生长指标的麦角固醇的色谱分析表明，与对照样品相比，霉菌生长受到显著抑制（83.24 - 99.99%），这导致霉菌毒素浓度降低。结果表明，添加肉桂、玫瑰草、橙子和留兰香精油对降低玉米赤霉烯酮浓度最为有效（99.10 - 99.92%）。脱氧雪腐镰刀菌烯醇分析证实，在应用所有测试精油时，该化合物的含量大幅降低（90.69 - 100%）。所得结果表明，精油在抑制玉米种子中霉菌生长以及降低霉菌毒素浓度方面具有巨大潜力。
