Objective: The aim of the study is to determine the enhancement of the essential oil potential and find a more effective method with fewer substances.Materials and Methods: For this purpose, Laurel and fennel essential oils obtained by the method of hydrodistillation in clevenger and their mixtures obtained by 2 different methods (Mix 1: separately obtained and mixed in appropriate proportions and Mix 2: obtained by placing together in the same glass flask) analyzed by Gc/Ms.Results: When the main components of the Mix-1 mixture are examined, the main components of R3/4D1/4, R1/2D1/2 and R1/4D3/4 combinations are trans-anethhole (54.53%, 32.47% and 17.46%, respectively) and 1.8- cineol (18.16%, 33.11% and 39.37%, respectively). In the second method (Mix-2), the main components of essential oils were examined. The main components of R3/4D1/4, R1/2D1/2 and R1/4D3/4 were trans-anethhol (64.83%, 46.23% and 24.93%, respectively) and 1,8-cineol (11.47%, respectively, respectively). 23.97% and 37.67%).Conclusion: As a result, it is clear that with essential oil blends, the components do not differ, while the proportions of the components do.
