    Aim of Study: It was aimed to determine the chemical composition, antioxidant and antibacterial activityof the Thymus praecox which distributed in the Kastamonu region.Material and methods: Spectroscopic and chromotographic analysis were applied in the determinationof the chemical composition. Thyme extracts were prepared using five different solvents. In Thymuspraecox, the presence of flavonoids using HPLC and the chemical content of essential oil using GC-MSwere investigated. The analyses of the mineral were determined in leaf and stem of thyme by ICP-OES.Antioxidant capacity was determined using two methods such as DPPH free radical scavenging and H2O2scavenging. Antibacterial activity on ten bacteria, Gram (+) and Gram (-) was tested using the disc diffusionmethod.Main results: Experimental results showed that thyme extracts have antibacterial activities against somebacteria. As a result, it was found that the most affected bacteria was S. aureus. Inhibition zone diameterwas determined to be between 8-12 mm. The effect of solvent on antibacterial activity, antioxidant capacity,total phenolic and total flavonoid amounts were observed.Highlights: These results showed that T. praecox has the potential to be used as a natural antimicrobialand antioxidant agent, and can be used as a natural supportive treatment.
