This study highlights, for the first time, the effect of Algerian nettle (Urtica dioïca L.) water extract against some phytopathogens bacteria. Results showed that water extract exhibited high level of total phenol content (261.7 ± 5.1 mg g−1 GAE) and a remarkable antioxidant activity (IC50 = 20.0 ± 0.6 µg mL−1) comparable to Trolox as reference (IC50 = 16.5 ± 0.5 µg mL−1). Moreover, results showed that water extract presented an interesting inhibition of some Gram-positive and Gram-negative phytopathogens’ bacteria. These results highlighted that secondary metabolites from Urtica dioïca could be an alternative pathway to synthetic pesticides for plant diseases control.

阿尔及利亚荨麻(UrticadioïcaL.)的水提物可能是控制某些植物病害的替代途径

这项研究首次强调了阿尔及利亚荨麻(UrticadioïcaL .)水提取物对某些植物病原菌的作用。结果表明,水提取物显示出高水平的总酚含量(261.7±5.1 mg g -1 GAE)和显着的抗氧化活性(IC 50  = 20.0±0.6 µg mL -1),与Trolox相比可作为参考(IC 50  = 16.5± 0.5 µg mL -1)。此外,结果表明,水提取物对某些革兰氏阳性和革兰氏阴性植物病原体细菌具有有趣的抑制作用。这些结果强调了来自荨麻的次生代谢产物 可能是控制植物病害的合成农药的替代途径。
