The essential oil (EO) from basil—Ocimum basilicum—was characterized, microencapsulated by vibration technology, and used to prepare a new type of packaging system designed to extend the food shelf life. The basil essential oil (BEO) chemical composition and antimicrobial activity were analyzed, as well as the morphological and biological properties of the derived BEO microcapsules (BEOMC). Analysis of BEO by gas chromatography demonstrated that the main component was linalool, whereas the study of its antimicrobial activity showed a significant inhibitory effect against all the microorganisms tested, mostly Gram-positive bacteria. Moreover, the prepared BEOMC showed a spheroidal shape and retained the EO antimicrobial activity. Finally, chitosan-based edible films were produced, grafted with BEOMC, and characterized for their physicochemical and biological properties. Since their effective antimicrobial activity was demonstrated, these films were tested as packaging system by wrapping cooked ham samples during 10 days of storage, with the aim of their possible use to extend the shelf life of the product. It was demonstrated that the obtained active film can both control the bacterial growth of the cooked ham and markedly inhibit the pH increase of the packaged food.

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

Abstract Pathogenic bacteria of the genus Legionella cause atypical pneumonia known as Legionnaires’ disease and flu – like disease known as Pontiac fever. As pathogens of the respiratory system, these bacteria represent a public health problem and there is a need for examine new alternative ways to inactivate them. These bacteria live naturally in water and are transmitted by infectious aerosols. To purify the air, essential oils that show antimicrobial properties are widely used. The anti-Legionella activity of five exotic essential oils and five Mediterranean essential oils characteristic for coastal Croatia was examined. Model organism used in experiments was L. pneumophila (strain 130b). This experiment was conducting with modified version of sealed plate method using a BCYE medium. The exotic essential oil with highest anti-Legionella activity was Niaouli essential oil, and the best anti-Legionella activity among Mediterranean essential oils showed Immortelle essential oil. Anti- Legionella activity of four main chemical compounds was examined and compound that show significant highest anti-Legionella activity was α – pinene. Volatile components of essential oils have a great potential as anti-Legionella agents and further research are needed.

Aim of this study was to investigate the antimicrobial properties of herbal plant essential oils (EOs) from selected Iranian plant species such as Ferulago angulata, Zataria multiflora, Cuminum cyminum, and Mentha longifolia against antibiotic-resistant Escherichia coli (E. coli) strains. For this purpose, the Escherichia coli strains, isolated from raw cow’s milk and local dairy products (yogurt, cream, whey, cheese, and confectionery products) collected from different areas of Hamedan province, Iran, were investigated for their resistance to antibiotics (i.e., streptomycin, tetracycline, gentamicin, chloramphenicol, ciprofloxacin, and cefixime). Thus, the E. coli strains were tested for their susceptibility to the above-mentioned essential oils. Regarding antibiotics, the E. coli strains were highly sensitive to ciprofloxacin. In relation to essential oils, the most effective antibacterial activity was observed with Zataria multiflora; also, the bacteria were semi-sensitive to Cuminum cyminum and Mentha longifolia essential oils. All strains were resistant to Ferulago angulata essential oil. According to the results, the essential oil of Zataria multiflora can be considered as a practical and alternative antibacterial strategy to inhibit the growth of multidrug-resistant E. coli of dairy origin.

Black pepper is a spice with a spicy taste and a distinctive aroma that has become known as the King of Spices. The distinctive aroma of black pepper comes from the volatile compounds that make up the essential oil of pepper. Black pepper essential oil has antimicrobial properties that can relieve respiratory infections and relieve muscle disorders. The acquisition of pepper essential oil from the distillation process is influenced by operating conditions. The aim of this study was to identify the composition of black pepper essential oil compounds using GCMS and to optimize the operating conditions (material size, solvent ratio, and distillation time). The method used to determine the optimum condition is using the Response Surface Method (RSM). The results showed that the highest yield of black pepper essential oil from this experiment is 5.14%. The empirical model was also suitable for the experiment and the optimum conditions for producing the maximum pepper oil yield 5,81% were 40 mesh of material size, 0.12 (g.ml-1) of solvent ratio and 162 minutes of distillation time. GCMS test results showed that the main constituents of pepper essential oil are caryophyllene, ocimene, limonene, carene, and a-pinene.
