TI  - Antioxidant Capacity and Essential Oil Composition of Hypericum thymopsis Boiss. (Hypericaceae) from Turkey
AB  - Antioxidant capacity and essential oil composition of Hypericum thymopsis Boiss. (Hypericaceae), an endemic species, distributed in Turkey was determined. The samples of three different populations were used for the analysis. Antioxi - dant capacity was determined by DPPH method from the leaves and flowers. Essential oil analysis was performed from areal parts of plant by gas chromatography (GC) and GC/mass spectrometry (MS). The major components of the essential oil were determined as α-pinene (31.86%), spathulenol (11.16%) and limonene (4.3%) in the specimen TA3004, α-pinene (28.07%), spathulenol (12.37%) and limonene (6.07%) in the specimen TA3014 and α-pinene (26.03%), limonene (14.83%) and spathu - lenol (9.74%) in the specimen TA3017. According to the 50% inhibition (IC50) values (μg/mL) the highest antioxidant values were measured in the methanolic extract of flowers.
