The antibacterial activities of the clove essential oil (C), turmeric essential oil (T) as well as clove and turmeric (CT) essential oil were analysed against some bacterial pathogens implicated in periodontal diseases using agar well diffusion. The bacteria include Klebsiella oxytoca, Bacillus subtilis, Pseudomonas flourescens, Pseudomonas aeruginosa, Klebsiella oxytoca, Enterobacter sp., Proteus mirabilis and Escherichia coli. At 15% concentration of the essential oils, both clove essential oil and the essential oil of clove and turmeric (CT) exhibited pronounced and varying degrees of growth inhibition zones against the bacteria (8.3+/-0.33-22.6+/-1.53 and 7.3+/-0.33-22.3+/-1.45). The MIC value for clove essential oil, tumeric essential oil and clove and turmeric (CT) essential oils ranges from 0.9-7.5%, respectively. The result shows that in general, clove essential oil has significantly greater zone of inhibition (mean) than tumeric essential oil. The bactericidal rate of clove essential oil against Klebsiella oxytoca and Bacillus subtilis was also determined. From our study, we can conclude that clove essential oil has more prevailing and sustainable antibacterial properties than turmeric essential oil even at a considerable low percentage. We recommend that clove essential oil not only has very promising potential for a broad-spectrum antibiotic drug against periodontal pathogenic bacteria. In addition, it can be used as an effective source of natural herbal antibiotics.

Medicinal plants are considered modern resources for producing agents that could act as alternatives to antibiotics in demeanor of antibiotic-resistant bacteria. The aim of the study was to evaluate the chemical composition and antibacterial activities of essential oil of Foeniculum vulgare (FV) against Pseudomonas aeruginosa and Bacillus subtilis. Gas chromatography mass spectrometry was done to specify chemical composion. As a screen test to detect antibacterial properties of the essential oil, agar disk and agar well diffusion methods were employed. Macrobroth tube test was performed to determinate MIC. The results indicated that the most substance found in FV essential oil was Trans-anethole (47.41 %), also the essential oil of FV with 0.007 g/ml concentration has prevented P. aeruginosa and with 0.002 g/ml concentration has prevented B. subtilis from the growth. Thus, the research represents the antibacterial effects of the medical herb on test P. aeruginosa and B. subtilis. We believe that the article provide support to the antibacterial properties of the essential oil. The results indicate the fact that the essential oil from the plant can be useful as medicinal or preservatives composition.

The purpose of this study was to determine the chemical composition and to evaluate the antioxidant and antibacterial effects of the Moroccan Artemisia herba-alba Asso essential oil against foodborne pathogens. The essential oil of Artemisia herba-alba was analyzed by gas chromatography coupled with mass spectroscopy. The antibacterial activity was assessed against three bacterial strains isolated from foodstuff and three bacterial strains referenced by the ATCC (American Type Culture Collection) using the disk diffusion assay and the macrodilution method. The antioxidant activity was evaluated using the DPPH (2, 2-diphenyl-1- picrylhydrazyl) method. The fourteen compounds of the Artemisia herba-alba essential oil were identified; the main components were identified as β-thujone, chrysanthenone, α-terpineol, α-thujone, α-pinene, and bornyl acetate. The results of the antibacterial activity obtained showed a sensitivity of the different strains to Artemisia herba-alba essential oil with an inhibition diameter of 8.50 to 17.00 mm. Concerning the MICs (minimum inhibitory concentrations), the essential oil exhibited much higher antibacterial activity with MIC values of 2.5 μl/ml against Bacillus subtilis ATCC and Lactobacillus sp. The essential oil was found to be active by inhibiting free radicals with an IC50 (concentration of an inhibitor where the response is reduced by half) value of 2.9 μg/ml. These results indicate the possible use of the essential oil on food systems as an effective inhibitor of foodborne pathogens, as a natural antioxidant, and for potential pharmaceutical applications. However, further research is needed in order to determine the toxicity, antibacterial, and antioxidant effects in edible products.

This review aims to determine the types of bases that can be used every day, which are effective and efficient as anti-inflammatory drugs. The research method used was to review the development of clove essential oil formulations that have been carried out using various concentrations of various types of bases including M / A type cream, A / M type cream, water soluble base, lotion, emulgel, hydrocarbons, hydrogels and absorbents. The recommended formulation is type M / A cream with a concentration of 5% clove flower essential oil. The types of bases studied were M / A cream, type A / M cream, water soluble base, lotion, emulgel, hydrocarbons, hydrogels and absorption properties which had good physical properties and did not irritate the skin of the test animals. This review refers to several national and international journals released in the last ten years, from 2010 to 2020.
