Antioxidant activities and Chemical composition of Marrubium vulgare L. essential oil from Tunisia
Keywords:
Marrubium vulgare, essential oil, chemical composition, antioxidant activity.Abstract
In this study, the essential oil of the aerial parts of Marrubium vulgare L. obtained by hydrodistillation
was analyzed by gas chromatography coupled to mass spectrometry (GC-MS) in order to determine
their chemical composition. Thirty-four (34) components in the oil of M. vulgare were identified. The
results demonstrated that the major components of the essential oil were -eudesmol (11.93%), -
citronellol (9.90%), citronellyl formate (9.50%) and germacrene D (9.37%). Antioxidant effectiveness was
examined by three different methods: The DPPH (1,1-diphenyl-2-picrylhydrazyl) assay, the -carotene
bleaching test and the reducing power assay. The results showed that this oil can be considered an
effective source of antioxidants of natural origin. This is the first report on chemical composition of M.
vulgare essential oil cultivated in Tunisia and the original study on the antioxidant activity of M. vulgare
essential oil.
