Abstract :Antioxidant capacity and essential oil composition of Hypericum thymopsis Boiss. insert ignore into journalissuearticles values(Hypericaceae);, an endemic species, distributed in Turkey was determined. The samples of three different populations were used for the analysis. Antioxidant activities was determined by DPPH method from the leaves and flowers. Essential oil analysis was performed from areal parts of plant by gas chromatography insert ignore into journalissuearticles values(GC); and GC/mass spectrometry insert ignore into journalissuearticles values(MS);. α-Pinene, spathulenol and limonene are determined as the major components of the essential oils. According to the 50% inhibition insert ignore into journalissuearticles values(IC50); values insert ignore into journalissuearticles values(μg/mL); the highest antioxidant values were measured in the methanolic extract of flowers.
