In this study, essential oil and fatty acids composition and antioxidant properties of Micromeria Myrtifolia, which is grown naturally in Ceylanlı village/Kırıkhan/Hatay region, were investigated. Micromeria Myrtifolia contains 10.12% by weight of moisture, 0.053% by weight of essential oil and 0.56% by weight of fixed fat, on dry matter. In the volatile oil analysis, thirty-four volatile components were identified. The essential oil is mainly composed of Caryophylene oxide, Caryophyllene, α-Curcumene, β-Cadinene,4-tert-butyl anisole, Nerolidol, Cadalin, and α-Cubebene. Eleven components were identified in fatty acid analysis. According to the analysis, the main components of fixed oil were palmitic acid (10.61%), linoleic acid (Omega 6) (8.46%), linolenic acid (Omega 3) (30.34%) and stearic acid (9.12%). The plant was extracted with methanol to determine its antioxidant capacity and total phenolic content. Total phenolics were found as 110.00± 0.00 mg Gallic acid equivalent g-1 of extract powder. DPPH free radical scavenging activity was found as IC50: 0.046±0.0035 mg ml-1. The Cupric reducing antioxidant capacity TEACCUPRAC:0.973 mmol TR g-1 was found from the Trolox calibration curve. The results were compared with the standard antioxidant compounds BHA and BHT. The results showed that the methanolic extract was rich in phenolic content and had an antioxidant activity close to synthetic antioxidants.
