Abstract
The chemical compositions of the essential oil of Asperula oppositifolia aerial parts were examined by gas chromatography/mass spectrometry (GC/MS); forty-two compounds were identified. Analysis of this essential oil revealed the presence of 2-(6,6-Dimethyl bicyclo[3.1.1]hepta-2en-2-yl) ethanol (17.16%), Decane (8.47%) , Dibuthyl phthalate (5.59%) and 1-Bromo Naphthalene(4%). The antioxidant activity of aerial parts of methanolic extract was studied by in vitro 2’2’-diphenylpicrylhydrazyl (DPPH) radical – scavenging activity, revealing that this plant could be used as new medicinal resource for antioxidant agent.
Key words: Chemical composition, essential oil, 2-(6,6-Dimethyl bicyclo[3.1.1]hepta-2en-2-yl)ethanol, Asperula oppositifolia ,antioxidant activity.
