Antimicrobial and antibiofilm studies on three endemic species of Verbascum L. (Scrophulariaceae) in Türkiye.

The consumption of traditional medicinal herbs has gained popularity as a viable alternative approach for addressing microbial infections or infectious structures. In this study, Verbascum detersile, Verbascum eskisehirensis, and Verbascum gypsicola endemic species belonging to the Scrophulariaceae family, spreading in Eskişehir and its surroundings, were collected from natural habitats and evaluated in terms of antimicrobial and antibiofilm activities. In biological activity studies, different concentrations of three plant extracts showed various antimicrobial and antibiofilm activities on selected standard microorganism cultures (Staphylococcus aureus ATCC 29213, Staphylococcus epidermidis ATCC 14990, Pseudomonas aeruginosa ATCC 27853, Candida albicans ATCC 90028, and Candida krusei ATCC 6258). It was observed that the selected three endemic Verbascum extracts had a minimum inhibitory and minimum biofilm eradication concentration value of 1250 µg/mL. [ABSTRACT FROM AUTHOR]
