“…Ils sont suivis par le bergamotène (8,48 %) qui est un sesquiterpène hydrocarboné (Ngom et al, 2014). Par contre, le 4-Isopropyl-1-methyl-2-cyclohexen-1-ol (cis) est le composé le plus abondant (15% des composés identifiés) dans l'huile essentielle de Cymbopogon schoenanthus (Hadef et al, 2015). Les différences d'inhibition observée dans notre étude ont été au préalable rapporté par des auteurs qui ont testé près de 14 huiles essentielles contre Molina laxa.…”

L’alternariose de la tomate est une maladie cryptogamique dévastatrice dans les zones maraichères du Burkina Faso. Tous les organes de la plante (tiges, feuilles, fruits) sont attaqués, entrainant une baisse importante du rendement et une dépréciation de la qualité de la production. Dans la présente étude, quatre huiles essentielles de plantes aromatiques locales (Cymbopogon schoenanthus, Lippia multiflora, Ocimum americanum, et Ocimum basilicum) ont été testées, pour évaluer leurs propriétés d'inhibition sur la croissance radiale du mycélium d’un isolat pathogène de Alternaria sp. Le test in vitro des doses de 100%, 50%, 10%, 5% et 1% a montré que toutes ces huiles essentielles possèdent une activité antifongique sur ledit isolat. Les taux d’inhibition des huiles essentielles sur la croissance du champignon étudié vont de 25,96% à 100%. La meilleure inhibition a été enregistrée avec l’huile essentielle de Cymbopogon schoenanthus, de Ocimum basilicum et de Lippia multiflora pour les concentrations supérieures à 1%. Il ressort donc de cette étude que trois huiles essentielles, stoppent la croissance mycélienne de l’isolat pour des doses allant de 5% à 100%. Ces huiles (Cymbopogon schoenanthus, Ocimum basilicum et Lippia multiflora) pourraient être utilisées pour la mise au point de phytopesticides afin d'atténuer l’utilisation intensive et hasardeuse des pesticides.Mots clés: Alternariose, activité antifongique, plante aromatique, tomate. English Title: Effects of four essential oils on radial mycelial growth of an isolate of Alternaria sp. in Burkina Faso Early blight of tomato is a devastating cryptogamic disease in the vegetable gardens in Burkina Faso. All plant’s organs (stems, leaves, fruits) are attacked causing a significant decrease in the yield and a depreciation of the quality of the production in the field. In the present study, four essential oils of aromatic plants (Cymbopogon schoenanthus, Lippia multiflora, Ocimum americanum, and Ocimum basilicum) were tested to evaluate the inhibition properties of these oils on the radial growth of the mycelium of an isolated pathogen of Alternaria sp. In vitro tests at doses of 100%, 50%, 10%, 5% and 1% showed that all these essential oils tested have antifungal activity on said strain. The inhibition rates of essential oils on the growth of the fungus studied range from 25.96% to 100%. The best inhibition was recorded with the essential oil of Cymbopogon schoenanthus, Ocimum basilicum and Lippia multiflora for applied concentrations more than 1%. It therefore emerges from this study that three essential oils stop the mycelial growth of the isolate for doses ranging from 5% to 100%. These oils (Cymbopogon schoenanthus, Ocimum basilicum and Lippia multiflora) could be used for the development of phytopesticides in order to reduce the intensive and hazardous use of pesticides.Keywords: Early blight, antifungal activity, aromatic plant, tomato.

“…In contrast, the content of sesquiterpenoid compounds was relatively low. Recently C. schoenantus from the eastern of Algeria was studied by Hadef et al (2015), the most important compound detected in leaves was 4-isopropyl-1-methyl-2-cyclohexen-1-ol (cis) (15%). As a result the study can say that the essential oil obtained from C. schoenantus showed significant variation in their chemical composition depending on geographical origin.…”

Hydrodistilled volatile oil obtained from the aerial parts of Cymbopogon schoenanthus cultivated near Illizi, Algeria, was analyzed by Gas Chromatography Mass Spectrometry (GC-MS) and Gas Chromatography -Flame Ionization Detector (GC-FID). More than twenty compounds were identified, representing 94.636% of the total oil. The major constituents of essential oil were piperitone (63.35%), β-eudesmol (9.305%) and elemol (6.915%). Isolated essential oil was tested for radical-scavenging ability using the stable 2,2-diphenylpicrylhydrazyl (DPPH) radical, the 2,2'-azino-bis (ABTS) radical and for reducing power ability with a test based on the reduction of ferric cations (FRAP). In all tests, oil did not show a prominent antioxidant activity. The screening of antimicrobial activity of oil was individually evaluated against representatives of gram-positive, gram-negative bacteria and fungi, using the agar diffusion method. All tested microorganisms were inhibited by the essential oil of C. schoenanthus.
