AbstractAspergillus parasiticus is one of the most common fungi which contaminates peanuts by destroying peanut shells before they are harvested and the fungus produces aflatoxins. The aim of this study was to evaluate the antifungal activities of seventeen essential oils on the growth of the aflatoxigenic form of A. parasiticus in contaminated peanuts from commercial outlets in Georgia. The agar dilution method was used to test the antifungal activity of essential oils against this form of A. parasiticus at various concentrations: 500; 1,000; 1,500; 2,000; 2,500 ppm. Among the seventeen essential oils tested, the antifungal effect of cinnamon, lemongrass, clove and thyme resulted in complete inhibition of mycelial growth. Cinnamon oil inhibited mycelial growth at ≥ 1,000 ppm, lemongrass and clove oils at ≥ 1,500 ppm and thyme at 2,500 ppm. However, cedar wood, citronella, cumin and peppermint oils showed partial inhibition of mycelial growth. Eucalyptus oil, on the other hand, had less antifungal properties against growth of A. parasiticus, irrespective of its concentration. Our results indicate that the aflatoxigenic form of A. parasiticus is sensitive to selected essential oils, especially cinnamon. These findings clearly indicate that essential oils may find a practical application in controlling the growth of A. parasiticus in stored peanuts.

The antifungal effect of aromatic plants (oregano, thyme, and Satureja) in dry form and as essential oils was evaluated in vitro (in potato dextrose agar (PDA)) and in bread against two phytopathogenic fungi found in food (Aspergillusniger and Penicillium). Gas and liquid chromatography were used to analyze essential oils attained by hydrodistillation of the aerial parts of the aromatic plants and of the dried plant aqueous solutions that were autoclaved for 20 min at 121 °C before analysis. Carvacrol, α-pinene, p-cymene, and γ-terpinene were the main components of the essential oils, whereas carvacrol, rosmarinic and caffeic acids were the main components of the water extracts. In vitro antifungal test results showed that the addition of plants in dry form had great antifungal potential against both fungal strains studied. Penicillium was more sensitive to the presence of aromatic plants than Aspergillus. Among the three plant species tested, thyme was the most potent antifungal against both fungi. For the bread product, all three aromatic plants studied showed inhibitory effects against both fungi. Results presented here suggest that oregano, thyme and Satureja incorporated in a bread recipe possess antimicrobial properties and are a potential source of antimicrobial ingredients for the food industry.

Boswellia Sacra

Frankincense essential oils from Boswellia sacra have been commonly used to treat microbial infections from as early as the 11th century. The main feature of the plant is its gum resin, from which it is possible to obtain essential oils. In the present study, we focused on the comparative study of the oils extracted from the resins of three different Boswellia sacra cultivars (Najdi, Sahli and Houjri). From each of frankincense resin three successive essential oil samples (Grade 1, Grade 2, Grade 3) were obtained. Houjri gum resin gave the lowest percentage (5%) of total essential oil content but showed the maximum number of volatile components in all three grades. Najdi Grade 2 essential oil showed a minimum inhibitory concentration (MIC) of 52 mg/mL toward relevant pathogens Staphylococcus aureus and Pseudomonas aeruginosa, and samples from Grade 2 of Sahily and Houjiri were particularly active against a dermatological strain Propionibacterium acnes, displaying MIC values of 0.264 and 0.66 mg/mL, respectively. Data obtained from in vitro studies showed that all essential oils had a significant antifungal effect against Candida albicans and Malassezia furfur, showing MIC values ranging from 54.56 to 0.246 mg/mL. This work aims to increase the number of substances available in the fight against pathogens and to combat the phenomenon of antibiotic resistance, encouraging the use of alternative resources, especially in non-clinical settings (farms, food processing, etc.).

Ammoides Verticillata

Background: Tomato is considered a model plant in genetics and is one of the most economically important crops of all those that exist in the world. Several species of fungi are reported on tomato fruit, causing damage both during cultivation and after harvest. Some of the appropriate actions that could be initiated to resolve the problem are to develop and search for new antimicrobial substances isolated from the bioactive natural products, such as essential oils. Aim and Objective: The aim of this work was to determine the chemical composition of essential oils of Ammoides verticillata, Allium sativum and Curcuma longa, to evaluate their in-vitro antifungal activities and in-vivo antifungal effect of essential oils to prevent the diseases caused by tomato. Materials and Methods: The essential oils obtained from aerial parts of plants were analyzed by GC/MS and tested for their antifungal activities against Penicillium expansum, Fusarium solani, Rhizopus stolonifer and Alternaria alternata using the radial growth technique method. The effectiveness in-vivo of the association between Allium sativum and Curcuma longa essential oils was also investigated on tomatoes inoculated by fungi. Results: The essential oil from A. verticilata was mainly composed of phenolic compounds (54.4%), the A. sativum oil was mainly composed of sulfur compounds (91.5%) and C. longa oil was dominated by oxygenated monoterpenes (82.0%). The obtained results in-vitro antifungal revealed that individual essential oils of A. verticillata and A. sativum were more active than the essential oil of C. longa against all screened microorganisms. An important antifungal effect of A. sativum and C. longa essential oils blend was obtained against P. expansum (100%), F. solani (95.2%), R. stolonifer (95.1%) and A. alternata (48.5%). Furthermore, A. sativum and C. longa essential oils blends have demonstrated promising in-vivo antifungal activity to control infection of tomato against P. expansum and R. stolonifer. Conclusion: A. sativum and C. longa essential oil blends can be used as a natural food preservative and alternative to chemical fungicides to protect stored tomato against many phytopathogens.

Antifungal Effect

  This work offers comparisons between stakeholder’s labor works before and during extraction of biomolecules extracted from Laurus nobilis in Morocco. The objective of this study was to determine some paths to follow in order to have a better extract that can inhibit or minimize the development of Ver-ticilium dahliae. For essential oils, we studied the effect of harvest region, harvest period, plant part, drying temperature, pressure of distillation, distil-lation temperature and fraction of applied essential oil. For extracts with organic solvents, we compared their effect by pursuing both techniques dur-ing extraction. The first one was about using an organic solvent for total ex-traction; while the second technique concerned a fractional extraction by using some solvents and pursuing an increasing polarity. The results showed that the degree of development inhibition in plant pathogen show a signifi-cant difference. Thus, these findings will be helpful in preparing a technical draft to be followed in the extraction of biomolecules from this plant in or-der to obtain better results in getting antifungal compounds.
