Chemical composition, antioxidant and antibacterial activities of the essential oil of mentha spicata l. from Algeria

Abstract

Hydrodistilled essential oil of Mentha spicata L., cultivated at Ghardaïa (Algerian Septentrional Sahara), was analyzed by GC and GC/MS. 29 components representing 96.43% of the essential oil were detected with cis-carvone oxide (44.06%), 1,8-cineole (15.32%), cis-dihydrocarvone (8.85%) and limonene (5.80%) as the major components. Antioxidant activity was investigated using ?-carotene/linoleic acid, DPPH·, ABTS cation radical decolorization and Metal chelating assays. Antibacterial activity was performed according to disc diffusion and minimum inhibitory concentration (MIC) methods.
