Artemisia, one of the largest genera in the Asteraceae family, is an important plant group found worldwide with versatile uses such as for pharmacological, food, and ornamental purposes. Artemisia verlotiorum, a member of this genus, grows naturally in the temperate regions of Turkey and is known to be on the pollen collection routes of bees, thereby affecting the biochemical composition of bee products. In this study, the phenolic content, antioxidant, and antimicrobial potential of extracts obtained from the A. verlotiorum plant using different methods were investigated to evaluate their potential applications in the apiculture sector. Within the scope of the study, various extracts were prepared from the plant using different solvents, and their total phenolic content was determined by the spectrophotometric method as Gallic Acid Equivalent (mg GAE/mL). The antimicrobial activity was tested against Candida albicans ATCC 10231, Staphylococcus epidermidis ATCC 12228, and Staphylococcus aureus ATCC 25923 strains using the disk diffusion method. The results of the analyses revealed that the total phenolic content of A. verlotiorum extracts varied within a wide range, from 0.244 ± 0.005 to 30.404 ± 0.364 mg GAE/mL, with statistically significant differences (p<0.05). In antimicrobial tests, the extracts showed efficacy against all tested microorganisms, with inhibition zone diameters observed to range from 3.00 ± 0.00 to 37.00 ± 1.00 mm. It was determined that the extraction methods and solvent types created a statistically significant difference in terms of inhibitory activity on microorganisms. These results indicate that the A. verlotiorum plant possesses a rich phenolic content and broad-spectrum antimicrobial activity. These findings of potent biological activity strongly support that A. verlotiorum extracts are a promising candidate agent for natural, effective, and eco-friendly control strategies against pathogenic microorganisms and parasites that threaten colonies in beehives
