In this study, the effect of structuring on some quality ingredients of Origanum onites L. plant belonging to Lamiaceae family, which is located in the natural flora of Akdeniz University campus area, was investigated. In the study conducted in 2011, the proximity of living areas to the construction site of the habitats where the plants grow naturally to construction, three different regions (A: West of dormitories, B: East of theology faculty, C: Southwest of sports Academy) were created and plant samples were collected from these regions in May-June, which is the flowering period of the plants. Total phenol, total antioxidant and total flavonoid contents in the leaves and flowers of the plants collected from these regions were examined. In O. onites flowers; the minimum total flavonoid content was obtained from region C (16.66mg/g) (p<0.001) and the highest IC50 value was obtained from regions B (0.69 mg/dry weight) and C (0.66 mg/dry weight) (p <0.01). In O. onites leaves, total flavonoid content was determined at least in the C region (20.13 mg/gr) (p <0.01). It was determined that the flavonoid and antioxidant contents in the flowers and leaves of the plants collected from the C region closest to the construction site were lower than those collected from other regions. Although the research area is limited, the effect of construction sites on plants has been found remarkable.
