In the current study, the antioxidative and in vitro antifungal properties of ten Lamiaceae herbs were estimated. Based on the results, the in vivo antifungal potential of oregano, sage, hyssop and lemon balm water extracts against Fusarium root rot in asparagus plants was evaluated. Water extracts of several herbs (0.5% and 2%, w/v) showed high DPPH radical scavenging activity, and oregano, sage and lemon balm extracts exhibited considerable suppression of Fusarium oxysporum f. sp. asparagi (Foa) in vitro. Regarding in vivo evaluation, asparagus plants treated with water extracts (20%, w/v) of the selected four herbs were inoculated with Foa. Four weeks after Foa inoculation, lower disease incidence and indices were observed in all the extract-treated plants compared to control. These effects could be attributed to reduced Fusarium population owing to fungistasis induced by the extracts in the rhizospheric soil. Consequently, dry weights of shoots and roots treated with herb extracts were observed to be higher than those in control. Evaluation of caffeic acid and rosmarinic acid as the possible antifungal properties present in the Lamiaceae herbs also showed a suppressive effect on Fusarium population in the in vitro analysis. From these findings, it can be concluded that water extracts of the selected four herbs have high antioxidative properties and antifungal potential against Fusarium oxysporum f. sp. asparagi. In this case, the presence of possible antifungal secondary metabolites such as caffeic and rosmarinic acid in the extracts could be related to this antifungal potential.

菊科草本植物水提取物对芦笋镰刀菌根腐病的抑菌作用

在当前的研究中，估计了十种唇形科的抗氧化和体外抗真菌特性。根据结果​​，评估了牛至，鼠尾草，牛膝草和柠檬香脂水提取物对芦笋植物镰刀菌根腐病的体内抗真菌潜力。几种草药的水提取物（0.5％和2％，w / v）显示出较高的DPPH自由基清除活性，牛至，鼠尾草和柠檬香脂提取物表现出对尖镰孢f的显着抑制作用。sp。芦笋（FOA）体外。关于体内评价，将选择的四种草药的用水提取物（20％，w / v）处理的芦笋植物接种Foa。Foa接种后四周，与对照相比，在所有提取物处理过的植物中均观察到较低的病害发生率和指数。这些影响可能归因于根际土壤中的提取物引起的真菌病，镰刀菌种群减少。因此，观察到用草药提取物处理的芽和根的干重高于对照。评价咖啡酸和迷迭香酸作为亚麻科中可能存在的抗真菌特性在体外分析中，草药还显示出对镰刀菌种群的抑制作用。根据这些发现，可以得出结论，所选四种草药的水提取物具有较高的抗氧化特性和对尖镰孢的抗真菌潜力。sp。芦笋。在这种情况下，提取物中可能存在的抗真菌次级代谢产物（如咖啡酸和迷迭香酸）可能与这种抗真菌潜力有关。
