Abstract: The objective of this work was to assess the fumigant and repellent effects of essential oils on adults of Callosobruchus maculatus and to identify the chemical composition of two of the tested essential oils. For the fumigation test, the oils of Schinus terebinthifolius, Piper aduncum, Syzygium aromaticum, Piper hispidinervum, Cymbopogon citratus, Cinnamomum zeylanicum, and the eugenol compound were tested at different concentrations on C. maculatus adults. For the repellency test, the oils of S. terebinthifolius, P. aduncum, P. hispidinervum, S. aromaticum, Jatropha curcas, and Ricinus communis were evaluated. In the fumigation test, it was observed that P. aduncum and eugenol showed the highest and lowest LC50s, of 169.50 and 0.28 μL L-1 air, respectively. In the repellency test, the oils of S. aromaticum and P. hispidinervum were repellent to C. maculatus. Gas chromatography coupled to mass spectrometry (GC-MS) analysis of these two oils identified 42 compounds, of which safrole was the main component of P. hispidinervum and eugenol of S. aromaticum. The essential oils of S. aromaticum, C. zeylanicum, and the eugenol compound are the most promising to control C. maculatus, via fumigation.

AbstractBackgroundTherapy combination is defined as disease treatment with two or more medication to acheive efficacy with lower doses or lower toxicity. Regarding its reported toxicities and efficacy, the Essential Oils (EOs) from Syzygium aromaticum (SA) and Pelargonium graveolens (PG) were combined for in vitro and in vivo assays and toxicities.MethodsThe Essential Oils and mixture were tested for in vivo/in vitro antioxidant and anti-inflammatory activities. The assays included the animal model of acute inflammation (carrageenan model), the protective effect on H2O2/Sodium nitroprissude induced stress in Tetrahymena pyriformis, and the in vitro antioxidant assays.ResultsThe chemical analysis of the investigated Oils has lead to the identification of Eugenol (74.06%), Caryophyllene (11.52%) and Carvacrol acetate (7.82%) as the major element in SA; while PG was much higher in Citronellol (30.77%), 10-epi-γ-Eudesmol (22.59%), and Geraniol (13.95%). In our pharmacological screening of samples, both Oils demonstrated good antioxidant effects. In vivo investigation of the antioxidant activity in the protozoa model (T. pyriformis) demonstrated a lesser toxic effect of EOs mixture with no significant differences when oxidative stress markers and antioxidant enzymes (MDA, SOD and CAT) were evaluated. On the other hand the in vivo model of inflammatory response to carrageenan demonstrated a good inhibitory potential of both EOs. The EOs Mixture demonstrated equivalent bioactivity with lower toxic effect and minimal risk for each compound.ConclusionsThe results from this study indicate that EOs mixture from SA and PG demonstrated promising modulatory antioxidant/anti-inflammatory effect, which suggest an efficient association for therapy.

Essential oils (EOs) are now a hot topic in finding modern substitutes for antibiotics. Many studies have shown positive results and confirmed their high antibacterial activity both in vitro and in vivo. Deservedly, there is an attempt to use EOs as a substitute for antibiotics, which are currently limited by legislation in animal breeding. Given the potential of EOs, studies on their fate in the body need to be summarized. The content of EO’s active substances varies depending on growing conditions and consequently on processing and storage. Their content also changes dynamically during the passage through the gastrointestinal tract and their effective concentration can be noticeably diluted at their place of action (small intestine and colon). Based on the solubility of the individual EO’s active substances, they are eliminated from the body at different rates. Despite a strong antimicrobial effect, some oils can be toxic to the body and cause damage to the liver, kidneys, or gastrointestinal tissues. Reproductive toxicity has been reported for Origanum vulgare and Mentha arvensis. Several publications also address the effect on the genome. It has been observed that EOs can show both genoprotective effects (Syzygium aromaticum) and genotoxicity, as is the case of Cinnamomum camphor. This review shows that although oils are mainly studied as promising antimicrobials, it is also important to assess animal safety.

Head Blight

Fusarium head blight caused by Fusarium oxysporum f. sp. Radicis-lycopersici (FORL) is a constraint to tomato cultivation in Korhogo, Côte dIvoire. To control this disease, the antifungal activity of essential oils extracted from certain plants was evaluated in comparison with that of a synthetic fungicide for use. In vitro tests were performed on the different life stages of FORL. The in vivo evaluations consisted in carrying out two modes of treatment (curative and preventive) on plants of a susceptible variety of tomato inoculated with FORL. The results showed that the essential oils significantly reduced the different life stages of F.oxysporum f. sp. Radicis-lycopersici (FORL) as did the synthetic product. Thus, the essential oil Cymbopogon citratus at concentrations of 4000 and 6000 ppm strongly inhibited in vitro the different stages of FORL. In preventive and curative treatment, the essential oils not only improved the growth parameters of tomato plants but also reduced the incidence and severity of diseases. Thus, it was found that Cymbopogon citratus (4000 ppm) in preventive treatment, and Banko plus (250 ppm) in curative treatment reduced the mortality rate of FORL up to 6.66% and improved the growth parameters and reduced the flowering time of the tomato plant.The essential oil of C. citratus could be used for biological control of F. oxysporum f. sp. Radicis lycopersici.

Background: Essential oils have been used for centuries. EOs are gaining increasing interest because of their acceptance by consumers and their safe status. For the first time, the effect of essential oils on the inhibition of lipases has been investigated in this work. Objective: We aimed in this study to investigate in vitro the inhibitory effects of the three essential oils of most used spices: Peppermint (Mentha piperita L.), cinnamon (Cinnamomum zeylanicum L.) and Cloves (Syzygium aromaticum L. Merr. et Perry) against Candida rugose lipase. In silico studies using molecular docking have been achieved to study the inhibition mechanism of major compounds of EO: menthol, carvacrol, eugenol and cinnamylaldehyde toward CRL. Methods: The inhibitory effect of three essential oils were determined by candida rugosa enzyme and pNP-L as substrate using spectrophotometry. Autodock vina was used for molecular docking with 50 runs. Results: We have found that these essential oils have a strong inhibitory effect with IC50 values 1.09, 1.78 and 1.13 mg/ml compared with Orlistat 0.06 mg/ml. The results show competitive inhibition for the three major compounds Menthol, Carvacrol and Eugenol with uncompetitive inhibition for Cinnamaldehyde. Different repetition ratios of hydrogen bonds and hydrophobic interactions were observed. The saved interactions were with His449, Ser209, Gly123, Gly124 and Phe344 for all molecules. Conclusion: These observations support using and considering essential oils and their major compounds as good sources for design new drugs to treat candidiasis and other diseases related to Lipases.

Management of Pyriculari agrisea by eco-friendly approaches is promising. In this study the essential oils from Coriander sativum (Coriander), Azadirachta indica (Neem) and Syzygium aromaticum (Clove) were tested against Pyricularia grisea in vitro by poison food technique. The pure culture of P. grisea was allowed to grow at 300ppm, 500ppm and 1000ppm concentration of essential oils on PDA medium. Clove oil was found most effective to inhibit mycelial growth completely at 300, 500 and 1000ppm after72 hrs, 96 hrs and 120 hrs. Next effective oil was observed neem oil followed by coriander oil. This indicated that clove oil is most effective against P. oryzae pathogen. Neem and coriander oil is less effective. The results of the current study indicated that each of the three essential oils tested, reduced the radial growth of P. oryzae.
