原始语种摘要: Extracts of the aerial parts and roots of the wild-growing medicinal plant Gentiana asclepiadea were analysed for their antimicrobial, antibiofilm, and antioxidant activity with quantification of the total phenolic and total flavonoid content. Antimicrobial activity was tested against pathogenic and spoilage bacteria, yeasts, and moulds using the microdilution method. The strongest antibacterial activity was detected on Bacillus species, where minimum inhibitory concentrations (MICs) of from 0.16 mg/mL to 5 mg/mL were obtained, while antifungal activity was low to moderate, with MICs between 1.25 and 20 mg/mL. In the crystal violet assay, the extracts inhibit 50% biofilm formation in the concentration range of from 2.12 to 37.04 mg/mL. Staphylococcus aureus, S. aureus ATCC 25923, and...
