Composition and in vitro antifungal activity of Bunium persicum, Carum copticum and Cinnamomum zeylanicum essential oils

Abstract

Essential oils of Bunium persicum (Parsi Zira), Carum copticum (Ajwain) and Cinnamomum zeylanicum (cinnamon) were tested in vitro as growth inhibitors against six forma special of Fusarium oxysporum. Minimum inhibitory concentration (MIC) and median effective concentrations (EC 50 ) values (µl/L) were also demonstrated. The antifungal activity of essential oils was assayed by poison food medium method (0, 100, 200, 300, 400, and 500 µl/L). Essential oils were extracted by means of hydro-distillation and afterwards, gas chromatography-mass spectrometry (GC-MS) analysis was performed to identify their components. The main constituents were cinnamaldehyd (77.51%), β-linalool (11.13%), α-cubebene (1.18%) and 1S, CIS-calamenene (1.06%) for C. zeylanicum, thymol (52.95%), γ-terpinene (13.53%), p-cymene (11.28%) in C. copticum and γ-terpinene (24.02%), cuminaldehyde (20.1%), paracymene (13.09%), benzenemethanol alpha-propyl (13.01%), cyclopentane, 2-methyl-1-methylene-3-(1-methylethenyl) (3.57%) in B. persicum. All three essential oils exhibited antifungal effect on the studied fungi species; but essential oil of C. zeylanicum was more effective. The growth of F. oxysporum f. sp. lycopersici, F. oxysporum f. sp. ciceri and F. oxysporum f. sp. melonis was completely inhibited by essential oil of C. zeylanicum at 200 ppm concentrations.

Effect of Filtered Torrefied Wood Powder Extract as a Plant Growth Retardant

“…Furan mixtures originate from cellulose, and phenolic mixtures originate from lignin (Zheng et al 2012). Additionally, the detected components have antibacterial, disinfection, deinsectization, and antioxidation functions (Hamed et al 2012;Kim et al 2014;Zekeya et al 2014). This is especially true for 5-methyl-2-furancarboxaldehyde, which is the most antibacterial component (Zekeya et al 2014).…”
