Lavandula dentata L. is a medicinal plant which is rich in natural’s products such as phenolic compounds. The aim of this work is to characterize the soil where grows Lavadula dentata L. them to quantify the phenolic compounds and antioxidant effects evaluation of flowers stems and leaves of the plant. The proportioning of total polyphenols was realized with Folin-Ciocalteu reagent, the quantification of flavonoids was performed by a method with aluminum trichloride and sodium hydroxide, and the condensed tannins were determined with the vanillin method under acidic conditions. Results showed that the soil survey has revealed heterogeneity in the surface horizon (instead of the exchange of the various elements) from one place to another in the region. The extraction of the various phenolic compounds has also provided a significant difference between the different plant organs from one station to another and an important antioxidant activity.
