Biological valorization and characterization of essential oil of Algerian Mentha spicata L.

Abstract

Main purpose of our work is to valorise Mentha spicata from the arid zone in Algeria by the study of it biological activities and chemical profile; antibacterial activity and antioxidant activity. Essential oil is characterized by GCMS. Fortyfour constituents, accounting for 98.41% of the total oil contents identified were carbon (42.23%) followed respectively by limonene (29.57%), 1,8-cineole (5.31%), β-pinene (3.54%). The antioxidant activity of the hydro distilled oil was studied using DPPH to determined IC50. The antibacterial activity of essential oils was tested against five microorganisms with the diffusion disc method on bacteria: Staphylococcus aureus ATCC 25923,Candida Albicans ATCC 10231, Escherichia coli ATCC 25922, Bacillus ATCC 11778, Pseudomonas aeruginosa ATCC 27853), diameters vary between 6 and 18 mm.
