Essential oils constitute a heterogeneous collection of chemical compounds. Their main characteristics are that they all synthesized by plants and are volatile and mostly soluble in ethanol. They have traditionally been obtained from plants and they have been widely used for insecticidal, medicinal and cosmetic purposes. Essential oils contains about 20–60 components at quite different concentrations and they are characterized by two or three major components at fairly high concentrations. Lately, the essential oils and various extracts of plants have gained special interest as sources of natural antimicrobial and antioxidant agents because of the resistance to antibiotics that some microorganisms have acquired and the possible toxicities of the synthetic antioxidants. Spices consumed daily in different types of food to improve flavors, since ancient times, are well known for their antioxidant and antimicrobial properties. During recent decades, numerous numbers of plants have been monitored for their possible role as repellents and insecticides. In this review, the chemical composition profile of some important medicinal plants was evaluated, then antimicrobial properties of a number of essential oils was compared. Antioxidant activity of some essential oils was also considered. Finally, essential oil repellent properties an an important characteristics was evaluated. Further investigation for available data related to the other biological properties of medicinal plants essential oil is recommended.DOI: http://dx.doi.org/10.3126/ijls.v9i2.12043 International Journal of Life Sciences 9 (2) : 2015; 9-13

In our previous work (Fabri et al. 2009), we showed that different extracts of Mitracarpus frigidus had significant antibacterial, antifungal and leishmanicidal activities. In order to increase our knowledge about this species, this work assesses the chemical composition and the in vitro biological activity of its essential oil. Thus, the essential oil obtained by hydrodistillation of the aerial parts of M. frigidus was analyzed by GC/MS. Among several compounds detected, 11 were identified, being linalool and eugenol acetate the major components. The essential oil exhibited a moderate antibacterial effect against Staphyloccocus aureus, Bacillus cereus, Pseudomonas aeruginosa and Enterobacter cloacae (MIC 250 µg/mL). On the other hand, it showed a strong antifungal effect against Cryptoccocus neoformans (MIC 8 µg/mL) and Candida albicans (MIC 63 µg/mL). Expressive activity against L. major and L. amazonensis promastigote forms with IC50 values of 47.2 and 89.7 µg/mL, respectively, were also observed. In addition, the antioxidant activity was investigated through DPPH radical-scavenging and showed a significative activity with IC50 of 38 µg/mL. The cytotoxicity against Artemia salina was moderate with LC50 of 88 µg/mL. The results presented here are the first report on the chemical composition and biological properties of M. frigidus essential oil.

The emerging multi-drug resistance in food borne pathogens and consumers demand for minimally processed fresh natural foods has paved the path for natural antimicrobials and antioxidants to be used in food industry. This work investigates the chemical composition, antimicrobial and antioxidant properties of essential oils of Lavandula stoechas and its fractions which were obtained from the Lavandula stoechas using apparatus Glass Oven B-585. GC/MS analysis of Lavandula stoechas essential oil has led to the identification of 27 components, of which camphor, fenchone, camphene, borneol, α- Pinene and 1,8-cineole, were the major components. Fractions 1 and 2 have displayed qualitative similarities; fraction 3 has showed a different chemical profile characterized by the presence of various oxygenated sesquiterpenes. In DPPH assay, the IC50 value of Lavandula stoechas and its fractions have varied between 0.8 and 1.6 µg/ml, while phosphomolybdenum assay of essential oils of Lavandula steochas, fraction 1, 2 and 3 have showed values in the order of 79 ± 4.4, 73.7 ± 3.7, 76.2 ± 5.5 and 148.2 ± 6.2 μg/ml respectively. The essential oil of Lavandula steochas was very active against Staphylococcus aureus and Listeria spp. Fractions 1 and 2 were moderately active, however fraction 3 recorded a weak effect against all bacteria’s. The Chloromphenicol antibiotic was very active against all bacteria’s, Gentamycin has expressed average activity against pathogens but the Penicillin has showed poor activity. Our results suggest that essential oils of Lavandula stoechas and fraction 3 demonstrated interesting biological properties that suggest its use as a new potential source of natural antioxidant and antimicrobial agents.
