Composition and Antioxidant Capacity of Essential Oils Obtained from Thymus vulgaris, Thymus pannonicus and Satureja montana Grown in Western Romania

Abstract:

The study describes the phytochemical profile along with the antioxidant properties of the essential oils (EOs) from Satureja montana, Thymus vulgaris and Thymus pannonicus, grown in western Romania. The chemical composition of the EOs was evaluated by GC-MS. The phytochemical profiles indicated that the T. vulgaris and S. montana EOs belong to the carvacrol chemotype, while the T. pannonicus EO belongs to the thymol/p-cymene chemotype. The DPPH radical-scavenging method was used to test the antioxidant activity. T. pannonicus EO showed the lowest antioxidant capacity (1009.83 mg mL-1 of DPPH inhibition), followed by the S. montana EO (861.09 mg mL”1) and T. vulgaris EO (783.87 mg mL-1). According to the data known to us so far, the antioxidant activity of the T. pannonicus EO has not been reported in other experiments. The results confirm the potential of using EOs as natural antioxidants, an alternative to the use of synthetic additives. Keywords: Thyme, Winter savory, Essential oil, GC-MS analysis, IC50
