Satureja hortensis essential oil: Phytochemical component and Antioxidant properties

The aim of this study was to investigate chemical composition and antioxidant effect of satureja hortensis essential oil.essential oil of aerial parts of satureja hortensis was prepared using a Clevenger type apparatus for 3 h. Analysis of essential oil constituents by gas chromatography- mass spectrophotometry was performed. Total phenol and free radical scavenging activity of EO were evaluated. 9 constituents which represented 94 % of satureja hortensis essential oil was identified by high amounts of beta elemene (50.87 %).Total phenolic content was determined by using Folin-Ciocalteu reagent (32.65 mg/g), which was presented as gallic acid equivalent in 1 g of sample. IC50 of EO and ascorbic acid in DPPH method were respectively 277.9 and 19.34 μg. The antioxidant activity results showed that satureja is a good source of natural oxidants.
