1 - Combined effect of essential oils from Clove (<i>Syzygium aromaticum</i> (L.) Merr. & L.M.Perry), Thyme (<i>Thymus vulgaris </i>L.) and Lemon peel (<i>Citrus limon</i> (L.) Osbeck) on anti-bacterial, cytotoxic and anti-inflammatory activitiesWalid Yeddes Islem Mejri Taycir Grati Affes Saber Khammassi Majdi Hammami Wissem Aidi-Wannes Moufida Saidani TounsiTrends in Phytochemical Research , العدد 1 , السنة 6 , زمستان 2022Essential oils are natural products composed of a mixture of volatile and aromatic compounds extracted from different organs of plants that have been widely studied for their antibacterial activities against pathogens.

In this study, clove, lemon peel and thyme essential oils and their mixture were assessed for their antimicrobial activities using a panel of pathogenic Gram-positive, and Gram-negative, strains. Cytotoxicity and anti-inflammatory activity were also evaluated. Lemon peel essential oil was characterized by the predominance of limonene. Eugenol was the main component in clove essential oil and thymol in thyme essential oil. Clove, lemon peel and thyme essential oils and their combination had potent antibacterial, cytotoxic and anti-inflammatory activities. This study demonstrates that the use of essential oils is an effective alternative for pathogenic bacterial control, alone or in combination with antibiotic therapy. تفاصيل المقالة -

Citrus peel essential oils can have an antifungal activity. The peel essential oils of seven species of Citrus, namely clementine, pummelo, tangelo, sweet orange, sour orange, tangerine and lemon, were extracted by steam distillation and subjected to chemical analysis to identify and evaluate the chemical constituents. Tangerine exhibited the highest yield (1.23%) followed by lemon (0.66%), clementine (0.56%), sweet orange (0.55%), tangelo (0.50%) and sour orange (0.47%). The lowest yield was obtained in pummelo (0.16%). The main compound in all Citrus essential oils was limonene with 62.1% for tangerine, 69.7% for lemon, 72.2% for tangelo, 76.4% for clementine, 89.8% for pummelo, 92.8% for sour orange and 94.1% for sweet orange. All these Citrus essential oils had a weak antifungal activity (MIC = 8000-12000 µg/ml) against Alternaria alternata strain. تفاصيل المقالة
