Chemical Composition of Essential Oil Extracted from Euphorbia Densa Schrenk and Evaluation Its Antioxidant Activity

Abstract

The essential oil have been extracted from the aerial parts of Euphorbia densa Schrenk from euphorbiacea family collected in south west of Hama in Syria by hydro-distillation using Clavenger type apparatus. The composition, the qualitative and quantitative analysis of the essential oil was achieved and characterized by means of GC-MS and comparing with the references in the literature. A total of 16 compounds representing 94% of the essential oil were characterized. The oil was dominated by four compounds representing the majority of the compenants: 1.8-ceniole (18.87%), carvacrol (13.32%), Linalool (13.61%), (E)-Caryophyllene (10.29%) The other compounds were mostly presented in low amounts. The antioxidant activity of the essential oil was evaluated
