Antifungal activity of essential oil from the fruits of Ammodaucus leucotrichus Coss. and Dur., in liquid and vapour phase against postharvest phytopathogenic fungi in apples

Abstract

The aim of this study was to evaluate the antifungal activity of essential oil (EO) from Ammodaucus leucotrichus fruits against three phytopathogenic fungi causing the deterioration for apples, including Botrytis cinerea, Penicillium expansum and Rhizopus stolonifer by using the poisoned food (PF) and the volatile activity (VA) methods. The antifungal test results indicated that the EO displayed significant potential of antifungal activity against the tested phytopathogenic fungi (p<0.05). In PF technique, the MICs (minimums inhibitory concentrations) were 0.5 µL/mL for B. cinerea and P. expansum and 1 µL/mL for R. stolonifer. Whereas, in VA assay, the complete inhibition of the mycelial growth of B. cinerea and P. expansum was observed at MIC= 0.125 µL/mL air, and that of R. stolonifer was observed at MIC = 0.25 µL/mL air. The overall results suggest that A. leucotrichus essential oil have a potential as antifungal preservatives for the control of postharvest diseases of apple.

IN-VITRO ANTIMYCOTIC ACTIVITY OF SELECTED ESSENTIAL OILS AND FUNGICIDES AGAINST Aspergillus niger AND Fusarium oxysporum

“…Essential oils have been used against post harvest fungi like Aspergillus and Fusarium spp. (Bishop & Thornton, 1997;Soliman & Badeaa 2002;Fandohan et al, 2004;Tullio et al, 2007;Tolouee et al, 2010;Manssouri et al, 2016). In corroboration to findings of present study Sharma et al (2016b) Mahmoud 1994;Bankole & Joda 2004;Mostafa et al, 2013).The activities of the essential oils reported to be fungicidal, as no growth was observed on subculturing the test pathogens onto PDA plates when treated with the oils.…”

Medicinal uses, phytochemistry and pharmacology of Ammodaucus leucotrichus

“…The hydro-distilled oil it was inactive against Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi [16]. Botrytis cinerea and Penicillium expansum showed a strong sensitivity to Ammodaucus leucotrichus essential oil at all concentrations [4]. 128 α-copaen-11-ol Aerial part [24] 129 Isolongifolan-8-ol Aerial part [24] The Essential oil showed in vitro, important antifungal activities against germination and sporulation spores.…”

“…(=Cuminum maroccanum P.H.Davis & Hedge) is the only specie of the genus Ammodaucus in the Apiaceae family is referred to as 'Kamune es sufi or akâman' in most of the north African countries, while in Algeria it is commonly known as "Moudrayga" and known as "Cumin chevelu" in French [4,5]. It inhabits the maritime sands of the Saharan and sub-Saharan countries of North Africa, including Morocco, Algeria and Tunisia extending to Egypt and the tropical Africa.…”

Studies on the antioxidant activity of essential oil and various extracts of Ammodaucus leucotrichus Coss. & Dur. Fruits from Morocco

“…Previous studies of aqueous extracts of A. leucotrichus were shown to inhibit the formation of calcium oxalate monohydrate crystals and also found to potently inhibit the nucleation, growth and aggregation phases of calcium oxalate crystallization [8]. It was also reported that the essential oils of A. leucotrichus exhibited the antimicrobial activities against bacteria, yeasts and filamentous fungi [9][10][11].…”
