| Title : | ANTIBACTERIAL AND ANTIOXIDANT ACTIVITIES OF THE ESSENTIAL OIL OF CUMINUM CYMINUM SEEDS |
| Abstract : | Cuminum cyminum (in arabic: Kemoun) is an important source of therapeutic, cosmetic, bio-food and technological agents. Ancient civilizations used this plant for therapeutic purposes. Extracts from this plant are nowadays strongly used in the industrial and research fields, particularly for the medicinal, pharmacological and cosmetological purposes. Bioactive molecules extracted from Cuminum cyminum may express biocidal activities and prove to be good candidates for new antioxidants. The objective of the present work is to evaluate the biological properties of this plant, including antibacterial and antioxidant effects. The seeds of cumin are harvested at the wilaya of Biskra, and stored in a dry place until their use. They were identified at Hassiba Benbouali University of Chlef. Essential oil is obtained by hydro-distillation using a Clivenger type device (AFNOR, 2000). The obtained sample is stored in sealed bottles at low temperature (4°C) and away from light. The antibacterial effect is assessed by the disc method. The minimum inhibitory concentration (MIC) is determined by standard methods. The antioxidant activity is evaluated by the DPPH free radical trapping method of the methanolic extracts. The essential oil of C. cyminum shows a better activity against Gram+ strains compared to Gram- strains. The determination of MICs leads to the conclusion that its activity can be triggered at a very low concentration. The reaction with DPPH gives an interesting IC50. This testifies to the ability of this essential oil to reduce free radicals. Thanks to the antibacterial activities that we have highlighted, cumin can be considered as a palliative that could replace certain antibiotics. Moreover, its antioxidant activity allows us to use it as a natural food additive. |
