Antimicrobial Efficacy and HPLC Analysis of Polyphenolic Compounds in a Whole-Plant Extract of Eryngium campestre

Due to the constant increase in number of plant diseases and lack available treatments, there has been a growing interest extracts over past few decades. Numerous studies suggest that extract molecules possess valuable antimicrobial activities, particularly against fungi bacteria. This suggests these biomaterials could potentially serve as attractive therapeutic options for treatment phytopathogen infections. In present study, we investigated analyzed methanolic Eryngium campestre L. whole using HPLC. The analysis revealed presence several polyphenolic constituents, with benzoic acid, catechol, quercetin, vanillic resveratrol, naringenin, quinol being most abundant. amounts constituents were determined be 2135.53, 626.728, 579.048, 356.489, 323.41, 153.038, 128.77 mg/kg, respectively. Furthermore, isolated identified different fungal bacterial isolates from symptomatic potato plants, which accessioned Rhizoctonia solani (OQ880458), Fusarium oxysporum (OQ820156) (OQ891085), Ralstonia solanacearum (OQ878653), Dickeya (OQ878655), Pectobacterium carotovorum (OQ878656). antifungal activity was assessed growth inhibitions (FGI) at concentrations 100, 200, 300 µg/mL. results showed lowest concentration tested (100 µg/mL), exhibited highest effectiveness R. an FGI 78.52%, while it least effective F. 61.85%. At tested, demonstrated oxysporum, FGIs 88.89% 77.04%, Additionally, displayed concentration-dependent inhibitory effect on all three pathogens. (3000 able inhibit pathogens, although inhibition zone diameter varied. Among D. sensitivity extract, largest concentrations. These findings highlight potential E. source natural agents controlling various Consequently, offers safer alternative currently employed protective methods disease management.
